Donald Trump has allied himself with a cast of characters and hangers-on who, should he win the presidency, would likely have his ear. Below is an updated guide -- first published in May -- to the people the Republican presidential nominee has chosen to surround himself with.

Stephen Bannon

The Trump Connection

Breitbart News chairman Stephen Bannon was named as the chief executive of the Trump campaign.

What You Need To Know

Under Bannon’s leadership, Breitbart News has recently made a “noticeable shift toward embracing ideas on the extremist fringe of the conservative right. Racist ideas. Anti-Muslim and anti-Immigrant ideas,” according to the Southern Poverty Law Center.

Several anonymous Breitbart staffers alleged that “the company’s top management was allowing Trump to turn Breitbart into his own fan website” and claimed the candidate paid the site in exchange for favorable coverage. (Bannon denied the allegation.)

After news surfaced that then-Breitbart reporter Michelle Fields had allegedly been manhandled by Trump’s campaign manager, Bannon sided with the campaign over his employee, leading to the defection of several staffers.

Several former Bannon employees have spoken out about his hiring by the campaign. Former Breitbart editor at large Ben Shapiro called Bannon a “legitimately sinister figure” who has led Breitbart News to embrace the “white supremacist alt-right.” Former Breitbart News spokesperson Kurt Bardella told Media Matters that Bannon is a “pathological liar” whose hiring signals a “dangerous" shift by the campaign.

Kellyanne Conway

The Trump Connection

Kellyanne Conway served as a senior adviser and pollster for the Trump campaign, and was recently named campaign manager.

What You Need To Know

Conway has long been involved in conservative politics, mostly as a pollster working with conservative groups like the NRA, Family Research Council and Republican candidates like Newt Gingrich and Michele Bachmann.

Conway once said that people “don’t want their kids looking at a cartoon with a bunch of lesbian mothers” and suggested the representation of same-sex parents in children’s programming was a “corrupting” influence.” She also once argued that “political correctness” could create a situation where there were “air traffic controllers who don’t speak great English” leading to “two planes crashing in the sky.”

She also argued that “revulsion towards men” is “part and parcel of the feminist movement” and that “baby girls [are] being killed just because they’re girls” in America.

David Bossie

The Trump Connection

Conservative activist David Bossie is taking a leave of absence from his job as president of activist group Citizens United to be the deputy campaign manager for Trump.

What You Need To Know

In 1992, then-President George H.W. Bush condemned Bossie and Citizens United for using what he called “filthy campaign tactics” against the Clintons during the 1992 presidential campaign. Following President Clinton’s election, Bossie used his role as Citizens United’s political director to operate “an information factory” that produced “a steady stream of tips, tidbits, documents, factoids, suspicions, and story ideas for the nation's press and for Republicans on Capitol Hill.”

Following the 1994 congressional elections, Bossie became a top investigator for the House Government and Reform Committee. The committee was involved in investigating Whitewater, the supposed scandal in which the Clintons were accused of profiting from a real estate deal. Numerous Whitewater investigations failed to turn up evidence to charge the Clintons with anything. But Bossie resigned from that position in the wake of a firestorm regarding his role in releasing selectively edited transcripts and video of conversations with Clinton confidant Webster Hubbell, which omitted statements that downplayed alleged wrongdoing by Hillary Clinton. Then-Speaker of the House Newt Gingrich said he was “embarrassed” by “the circus” that went on at the committee.

Bossie returned to Citizens United, where he has been president since 2000. The group’s film Hillary: The Movie prompted the Supreme Court case Citizens United v. FEC, which resulted in the 5-4 decision that has led to nearly unlimited campaign spending in elections.

More recently, Citizens United has been pushing for the release of Hillary Clinton’s communications from the State Department when she was secretary of state, and the organization is a party in several lawsuits demanding Clinton-related materials from the agency. In the course of making those requests, Citizens United has often insinuated -- without evidence -- that wrongdoing took place. Bossie’s deceptive work is frequently cited in major media outlets.

Paul Manafort

The Trump Connection

Republican strategist Paul Manafort was hired by Trump as a senior aide to his political campaign. Manafort was later promoted to campaign chairman and chief strategist.

What You Need To Know

Manafort was partners with Roger Stone in the lobbying and consulting firm Black, Manafort, Stone and Kelly. After a congressional investigation, Manafort admitted that the work he performed after receiving consulting fees was “influence peddling.”

Manafort and his firms have worked with several unsavory clients including “a business group tied to Ferdinand Marcos, the dictator of the Philippines; Viktor Yanukovych, the ousted Ukrainian president and ally of Vladimir Putin; and Lynden Pindling, the former Bahamian prime minister who was accused of ties to drug traffickers.”

During the Republican primaries, Manafort accused Sen. Ted Cruz’s campaign of engaging in “Gestapo tactics” in order to win over convention delegates.

Manafort’s consulting work on behalf of a Ukrainian political party has come under scrutiny as a result of his role in the Trump campaign.

The Associated Press reported that Manafort “helped a pro-Russian governing party in Ukraine secretly route at least $2.2 million in payments to two prominent Washington lobbying firms in 2012, and did so in a way that effectively obscured the foreign political party's efforts to influence U.S. policy.”

The New York Times reported that “handwritten ledgers show $12.7 million in undisclosed cash payments designated for Mr. Manafort” by the pro-Russian political party he consulted for in Ukraine.

Roger Stone

The Trump Connection

Republican dirty trickster Roger Stone is a longtime Trump ally. Stone worked on his campaign until August of 2015, continues to serve as a prominent advocate for Trump’s candidacy, and regularly speaks with Trump, including recommending top aide Paul Manafort to the campaign.

What You Need To Know

In addition to his political dirty tricks, Stone has an extensive history of violent, racist, and sexist comments. He started an anti-Hillary Clinton group in 2008 with the acronym “C.U.N.T.,” and has called for her to be executed. He called cable news commentators a “stupid negro” and “Mandingo,” and he promotes conspiracy theories about the Clinton and Bush families murdering dozens of people. His next book is about how the Clintons purportedly murdered JFK Jr. “because he was in the way.”

Stone’s racist and sexist tweets resulted in him being banned from appearing on CNN and MSNBC.

While advocating for Trump, Stone has peddled several outlandish conspiracy theories. He accused the Clintons of murdering several more people, argued that the 2016 election will be “rigged” via the manipulation of voting machines, and alleged that a top Clinton campaign aide was connected to the 9/11 terrorist attacks. Stone also attacked the family of Captain Humayun Khan, who was killed in Iraq in 2004.

Alex Jones

The Trump Connection

Conspiracy theorist radio host Alex Jones has been one of Trump’s loudest and most passionate supporters. And the feeling is apparently mutual. In addition to promoting Trump on his show incessantly, Jones hosted Trump for an interview, praised him as a “George Washington” figure, and encouraged listeners to donate to his campaign. (During the appearance, Trump praised Jones for his “amazing” reputation and promised, “I will not let you down.”) Trump confidant Roger Stone has also become a regular on Jones’ show, and the two worked together to organize protests on Trump’s behalf at the Republican convention. After Trump essentially clinched the nomination, Stone went on Jones’ show and told the host, “Trump himself told me that he has seen so many of your supporters and listeners at his rallies,” adding, “I’m certain that he is grateful for your support.”

What You Need To Know

Alex Jones is a self-described “founding father” of the “9/11 truth movement” who believes that the terrorist attacks were a “false flag.” Jones also has promoted conspiracy theories alleging that events like the Sandy Hook Elementary shooting, the Boston Marathon bombing, and the Aurora movie theater shooting were all government-orchestrated attacks.

Jones publicly asked Trump to raise the conspiracy of the general election being “rigged,” which the candidate did days later. He praised Trump as being “totally synced” with the conspiracy theory movement and said it is “surreal to talk about issues here on air and then word-for-word hear Trump say it two days later.”

General Michael Flynn

The Trump Connection

Retired Army Lt. General Michael Flynn, former head of the Defense Intelligence Agency, is reportedly “a trusted Trump adviser and go-to man on intelligence and national security.”

What You Need To Know

Flynn was forced out of his position in 2014 after clashing with senior officials. He has complained that “‘political correctness’ has prevented the U.S. from confronting violent extremism, which he sees as a ‘cancerous idea that exists inside of the Islamic religion.’” Flynn accuses the U.S. government of concealing “the actions of terrorists like bin Laden and groups like ISIS, and the role of Iran in the rise of radical Islam.”

Flynn has publicly supported Trump’s idea that the families of terrorist suspects should be killed, and he also backs Trump’s proposal for a ban on Muslim travel to the United States. Flynn has written that “fear of Muslims is RATIONAL.”

In 2015, Flynn flew to Moscow and was filmed having a formal dinner with Vladimir Putin. The Daily Beast reported that “Pentagon brass were taken by surprise that he didn’t notify the department.”

Flynn was paid by the state-funded Russian television network RT for his appearance at the network’s anniversary gala.

Flynn spoke on Trump’s behalf at the Republican National Convention, saying that “war is not about bathrooms” in reference to controversy over anti-transgender laws. He also retweeted an anti-Semitic pro-Trump message which read in part, “Not anymore, Jews. Not anymore.” He later described the incident as “a mistake.”

Rudy Giuliani

The Trump Connection

Trump told Fox News that former New York City mayor and failed presidential candidate Rudy Giuliani might be his choice to head up a commission to review his proposal for a temporary Muslim ban.

What You Need To Know

Giuliani has a long history of anti-Muslim comments and statements. He argued in favor of Sen. Ted Cruz’s (R-TX) idea that one way to fight terrorism is to “patrol and secure Muslim neighborhoods,” said sexual assault in Germany proved that “these [Syrian] refugees are inherently a problem,” and praised Rep. Peter King (R-NY) for holding anti-Muslim hearings in Congress.

Speaking before Trump at a campaign rally, Giuliani said, “Under those eight years before Obama came along, we didn’t have any successful radical Islamic terrorist attack in the United States,” omitting the September 11, 2001, attacks. PolitiFact rated this claim “false.”

Ed Klein

The Trump Connection

Disgraced journalist Ed Klein said he has known Trump for 35 years and claimed, “I understand him better than most people outside his immediate family.” Klein recently had lunch with Trump as he campaigned in Indiana. Trump has repeatedly promoted Klein’s books on his Twitter account.

What You Need To Know

Journalists have described Klein’s columns and books attacking the Clintons and Obamas as “fan fiction” and “smut.” He has launched numerous unfounded smears, including the claim that Chelsea Clinton was conceived when Bill Clinton raped Hillary (he later walked back the allegation). Publisher HarperCollins reportedly dropped Klein’s Blood Feud because it “did not pass a vetting by in-house lawyers.” Klein has repeatedly distorted quotes in his work, and even conservative figures have expressed skepticism about the veracity of his reporting.

Jeffrey Lord

The Trump Connection

Lord, a contributor to the conservative American Spectator, has been a big booster of Trump’s candidacy. CNN hired Lord to present a pro-Trump point of view. According to Lord, Trump helped land him the gig. ThePatriot-News reported last year, “Lord said Trump complained to CNN execs that the network only featured commentators who didn't get him, so CNN asked The Donald who in the world of conservative media he would suggest, and he said Jeffrey Lord.”

What You Need To Know

Lord infamously tried to prove that a black man who was beaten to death was not technically lynched, a position that was even condemned by his colleagues at the Spectator. During his CNN appearances, Lord has defended Trump’s attack on Mexican immigrants as criminals and rapists, excused Trump’s failure to disavow the KKK, and described the Klan as a “leftist terrorist organization.”

Lord blamed the pro-choice movement for gun violence and attacked the family of deceased Army Captain Humayun Khan for speaking at the Democratic National Convention. He also echoed the Trump campaign by promoting the conspiracy theory that the election “could be stolen.”

Ben Carson

The Trump Connection

Carson endorsed Trump after he dropped his presidential bid and was then tasked with being Trump’s liaison between his campaign and Speaker Paul Ryan. Carson also apparently had some role in Trump’s vice presidential selection team.

What You Need To Know

Carson has caused controversy with a series of bizarre and offensive comments as an author, a Fox News contributor, and during his short-lived presidential campaign. During a Fox News appearance, Carson infamously compared marriage equality supporters to those who would advocate bestiality and pedophilia, and argued in his 2012 book that marriage equality could destroy America “like the fall of the Roman Empire.” Carson also claimed that the Egyptian pyramids were built to store grain, said being gay was a “choice,”described Obamacare as “the worst thing that has happened in this nation since slavery,” and argued that Jewish people could have prevented the Holocaust if they had guns.

Speaking on stage at the Republican National Convention, Carson compared Hillary Clinton to “Lucifer.”

Michael Savage

The Trump Connection

Radio host Michael Savage was an early backer of Trump in the conservative media who has describedhimself as “the architect of Trump’s messaging." Trump has appeared on his program multiple times -- in one appearance, Savage offered himself up to head the National Institutes of Health (NIH), a suggestion that Trump described as “common sense.”

What You Need To Know

Savage has a long history of outrageous and violent rhetoric. In 2008, he warned, “I fear that Obama will stir up a race war … in order to seize absolute power.”

Savage also claimed that President Obama “wants to infect the nation with Ebola” and is gearing up the government to “fight a war against white people.” Savage accused Obama of engaging in “genocide” against the white race.

Savage has described PTSD and depression sufferers as “weak” and “narcissistic” “losers.” Referencing military veterans suffering from PTSD, Savage said, “no wonder ISIS can defeat our military.”

Additionally, Savage has called for a “revolution” in response to multiculturalism, said “I’d hang every lawyer who went down toto Guantanamo” Bay, accused President Obama of being the “new Mao,” theorized that Democrats would declare martial law, and said “the radical left and the radical Muslims are natural blood brothers.”

Savage and Trump swapped notes on the conspiracy theory that Justice Antonin Scalia was murdered.

Ann Coulter

The Trump Connection

Conservative columnist Ann Coulter has repeatedly promoted Trump’s candidacy. Trump called Coulter’s anti-immigrant book, Adios, America! “a great read.” In return, Coulter said she believes that Trump’s anti-immigrant rhetoric was inspired by her.

What You Need To Know

Coulter has developed a reputation over the years for making hateful and disgusting public comments, often with a bigoted message that even conservatives have recoiled from. The conservative National Review dropped her column when, after 9/11, she said America should “invade their countries, kill their leaders and convert them to Christianity.”

Coulter’s book was apparently modeled on the rhetoric of white nationalists and other anti-immigrant extremists, and she credited white nationalist Peter Brimelow as an “intellectual influence” on her work.

While defending Trump, Coulter called South Carolina-born Governor Nikki Haley an “immigrant” who “does not understand America’s history,” and made derogatory attacks on Jews while complaining about Trump’s rivals in a primary debate.

She has also regularly offered bigoted anti-immigrant rhetoric, including suggesting that immigrants are more dangerous than ISIS and that “‘real’ Hispanics are on welfare.”

Laura Ingraham

The Trump Connection

Radio host Laura Ingraham has been a staunch supporter of Trump’s candidacy and has praised his anti-immigrant rhetoric. She once compared Trump to Abraham Lincoln.

What You Need To Know

Ingraham has often used her show to demonize and attack immigrants. Ingraham said Mexicans “have come here to murder and rape our people,” called the children of undocumented immigrants “anchor fetuses,” andsuggested that deported immigrants attempting to re-enter the country should be “shot.”

Speaking at the Republican National Convention, Ingraham demanded that Trump’s primary rivals “honor your pledge” and “support Donald Trump now.”

Chris Christie

The Trump Connection

New Jersey governor Chris Christie endorsed Trump after he dropped out of the campaign and has served as a leading surrogate for the candidate

What You Need To Know

Christie has become infamous for his public arguments with voters and other figures. He told a critical voter he was “a real big shot shooting your mouth off,” called a reporter “a complete idiot,” and told a resident asking about stalled rebuilding efforts after Superstorm Sandy to “sit down and shut up.”

In addition to his demeanor, Christie’s administration was involved in the Bridgegate scandal, where his subordinates conspired to block traffic on the George Washington Bridge as payback for political slights against the governor.

Larry Kudlow

The Trump Connection

Larry Kudlow was part of the Office of Management and Budget in Reagan’s first term, and is now a columnist and on-air personality for CNBC. Trump enlisted Kudlow (along with Stephen Moore) to work on changes to his economic plans.

What You Need To Know

Kudlow was a big supporter of George W. Bush’s economic policies and was infamous for missing the warning signs of the coming economic meltdown.

Kudlow dismissed people concerned about the real estate bubble in the mid-2000s as “bubbleheads who expect housing-price crashes.” In December 2007, as the National Bureau of Economic Research marked the beginning of the Great Recession, Kudlow wrote, “there’s no recession coming.”

Stephen Moore

The Trump Connection

Conservative economic columnist Stephen Moore was enlisted, along with Larry Kudlow, to tweak Trump’s economic policy in the general election.

What You Need To Know

Like Kudlow, Moore has a terrible track record when predicting the effect of both conservative and progressive policies on the economy. He also regularly makes false claims to attack policies like taxes, regulation, the minimum wage, and Obamacare.

The editorial page director of the Kansas City Star declared she “won’t be running anything else from Stephen Moore” after he used false employment numbers in a column attacking economist Paul Krugman.

In a column promoting Trump's candidacy, Moore wrote, “It is striking that Trump is the anti-Obama in every way.”

Scottie Nell Hughes

The Trump Connection

Scottie Nell Hughes is a cable news pundit and CNN contributor who has often spoken in defense of Donald Trump. Glamour notes she “has been on the front line for Trump campaign since she introduced him at a September mega rally in Dallas.”

What You Need To Know

Hughes was previously the news director for the “Tea Party News Network.” She uses odd logic to launch defenses of Trump’s actions.

When some called for riots at the Republican convention in defense of Trump, Hughes told CNN “it’s not riots as in a negative thing.” Hughes said that Trump’s statement that women should be punished for abortions had been “misconstrued,” and that the media paying attention to Trump’s sexist tweets is unfair.

Hughes lamented that Democratic vice-presidential nominee Sen. Tim Kaine (D-VA) uses Spanish in his speeches, saying, “I’m hoping I’m not going to have to kind of start brushing up back on my Dora the Explorer to understand some of the speeches given” during the Democratic convention.

She also claimed that Hillary Clinton’s presidential nomination is “tearing down men.”

Pat Caddell

The Trump Connection

Caddell has reportedly been “speaking regularly” with campaign chief executive Stephen Bannon about “what Trump could do in the coming weeks to expand his appeal, in particular with Democrats and independents.”

What You Need To Know

Caddell worked for President Jimmy Carter, but, as the Washington Post notes, his "ties to the Democratic Party have frayed in recent decades as he has become a well-known face on Fox News and more closely associated with independent candidates.”

Caddell has been a frequent guest on Breitbart News’ radio show, Breitbart News Daily, where he has engaged in conspiracy theories about polls being skewed against Donald Trump, and described the Obama White House as “Nixon on steroids.”

Caddell also said reporters were supposedly making themselves “the enemies of the American people” for exhibiting bias against Trump. As the Post pointed out, Caddell’s commentary has regularly been promoted by Breitbart News.

For years, Caddell’s commentary has often aligned far more with his conservative Fox News colleagues than anyone purporting to be a Democrat. (In one 2011 Fox Business appearance, he described the Democrats as being his “former” party.)

In 2010, along with Doug Schoen, Caddell wrote an op-ed calling on President Obama not to seek a second term and argued, “The president has largely lost the consent of the governed.”
