WASHINGTON (AP) — The Latest on the U.S. presidential transition (all times EST):

9:45 p.m.

President-elect Donald Trump is back on Twitter, taking on the protesters who have gathered in cities across the nation since his election.

Trump tweets: "Just had a very open and successful presidential election. Now professional protesters, incited by the media, are protesting. Very unfair!"

Thousands have been gathering in cities from New York to Dallas to San Francisco to voice opposition to Trump's election.

Trump's complaint Thursday about the media echoes the rhetoric of his campaign, when he railed against the press as "disgusting" and "dishonest."

A few minutes earlier, Trump was more positive about his trip to Washington, tweeting: "A fantastic day in D.C. Met with President Obama for first time. Really good meeting, great chemistry. Melania liked Mrs. O a lot!"

Billionaire conservative donor Charles Koch (kohk) says the election shows America is "more deeply divided than at any point in my lifetime."

Koch and his brother, David, oversaw policy and politics groups that spent about $250 million in the two years ahead of the election, much of it on a successful drive to keep the Senate in Republican hands. However, the brothers did not support Donald Trump and withheld their money from the presidential race.

In an email Thursday to his groups' donors and employees, obtained by AP, Koch does not specifically mention Trump but says his group would work to find common ground with any elected official.

Koch says the election "made clear that Americans are angry about a rigged economy and political system that's driving our country toward a two-tiered society," he wrote.

Donald Trump has won Arizona's presidential contest and its 11 electoral votes.

The Republican president-elect had a solid lead over Hillary Clinton on election night, but a winner wasn't declared because there were so many uncounted votes. The latest batch of returns tabulated Thursday made him the clear winner.

It extends a 20-year winning streak for Republican presidential candidates in Arizona. Bill Clinton was the last Democrat to take the state, winning in 1996.

Hillary Clinton was closer to gaining Arizona than Barack Obama, who lost by more than 9 percentage points during his two runs for president. She is losing by 4 points.

Arizona was one of three races that had yet to be determined from the Tuesday election. Michigan and New Hampshire remain too close to call.

Donald Trump has picked a longtime friend and private equity executive to lead his inauguration efforts.

Tom Barrack, who founded California-based firm Colony Capital, has been selected to serve as chairman of the President-elect's inaugural committee. That's according to two sources with direct knowledge of the decision who spoke on the condition of anonymity to share internal discussions.

Barrack has been an aggressive public supporter of Trump throughout the campaign. He was among the primetime speakers at Trump's nominating convention this summer.

The inaugural chairman is responsible for raising millions of dollars to fund the inauguration, which includes several major parties and an extensive entertainment program.

Barrack's office declined a request for comment.

He told CBS "This Morning" on Thursday that Trump was like an ultimate fighter during the campaign who used "whatever tools necessary to convey a really disruptive message." He said America would see "a softer, kinder" Trump now that he's won the presidency.

The president of the United Auto Workers says the union's views on trade align with Donald Trump's, and he'd like a meeting with the president-elect to talk about it.

Dennis Williams says he agrees with Trump's call for scrapping the North American Free Trade Agreement, which has sent auto jobs to Mexico. He also backs Trump's proposal for a 35 percent tariff on vehicles imported from Mexico.

The UAW has historically supported Democratic candidates and endorsed Hillary Clinton this year. But Michigan, which has the most auto workers of any state, narrowly voted for Trump in unofficial results. Internal polling of union members prior to the election showed 28 percent going for Trump with 6 percent undecided. Williams says Trump's total may actually have been slightly higher than the 31 percent who voted for Mitt Romney and 33 percent who went for John McCain.

As President-elect Donald Trump puts together his White House, Republican National Committee Chairman Reince Priebus and top campaign aide Kellyanne Conway are emerging as possible picks for chief of staff.

That's according to two people familiar with the transition planning.

Conway, a prominent Republican pollster, served as Trump's third campaign chief of staff and developed a strong rapport with the candidate. Priebus embraced Trump after his nomination, despite concerns among other Republicans, and worked his way into his inner circle.

A third person with knowledge of the transition process says conservative media executive Steve Bannon is also in the mix for chief of staff. However, others insist Bannon would not have a White House role.

Those involved in the process insisted on anonymity because they were not authorized to discuss the planning publicly. A decision on chief of staff is expected in the coming days.

Federal officials have imposed temporary flight restrictions over Vice President-elect Mike Pence's current home at the Indiana governor's residence.

The FAA generally issues temporary restrictions when there's a special event or hazardous condition. Similar limits have been issued for around Trump Tower in New York City.
