Democratic presidential candidates faced-off in the second debate Saturday night at Drake University in Des Moines, IA. Former Secretary of State Hillary Clinton, Vermont Sen. Bernie Sanders and former Maryland Gov. Martin O’Malley answered questions in the shadow of Friday's terrorist attacks in Paris, a development that shifted the focus of the debate.

Here's a recap of everything you need to know:

10:50 p.m. EST: Closing Statements

O'Malley: Asks people to visit his website and says he needs support. Also says that the country needs new leadership and that the U.S. can confront any challenge.

Clinton: It's not about me, it's about the American people, Clinton says. When she talks about the president, she also uses the pronoun "she" to applause. Also asks people to visit her website and for Iowans to caucus for her.

Sanders: Inequality, campaign finance, childhood poverty, paid family and medical leave are issues that call for "a political revolution." And another pitch to visit his website.

10:45 p.m. EST: What Crisis Have You Experienced That Will Prepare To Be President?

Clinton: She says advising President Barack Obama on the killing of Osama bin Laden.

O'Malley: No crisis can prepare to be commander-in-chief he says but points to his experience as the top executive in Baltimore and the state of Maryland.

Sanders: Sanders points to a moment of bipartisanship when crafting legislation for veterans.

10:38 p.m. EST: Single Payer v. Obamacare

Sanders enthusiastically supports single-payer health care.

When asked about her previous support of a single-payer type of system in the 90s, Clinton said "the revelation never came." She then said Obamacare is a great start.

Sanders turns and asks Clinton if she thinks health care a "right for all people?"

10:36 p.m. EST: Free College

Sanders was asked if his goal of debt-free college is not worth it because about one-third of college students don't graduate. Sanders said it's an extremely important investment.

Sanders is the only one on the stage who supports free college.

Clinton says community college should be free and debt-free for students at public universities.

"I disagree with free college." Clinton said. "I don't think the American people should pay for Donald Trumps kids to go to college."

10:30 p.m. EST: Race

There's not a lot of disagreement on this issue.

O'Malley says "Black Lives Matter."

Sanders talks about criminal justice reform.

Clinton mentions Tamir Rice, Eric Garner and Trayvon Martin. She says she's met with their mothers.

In light of protests at the University of Missouri. Clinton adds: "I do believe on college campuses there should be enough respect so people hear each other."

10:23 p.m. EST: Clinton's Emails

Sanders was asked if Clinton's emails are a problem are not: "I was sick and tired of Hillary Clinton's emails and am still sick and tired of Hillary Clinton's emails."

Said he wants the media to ask "Why the middle class is disappearing, why we have more people in jail...and the major issues facing America."

Returning the moment of unity, Clinton says she gives "Sanders a lot of credit for lighting a fire."

10:16 p.m. EST: Guns and Then Back To Wall Street

After a short conversation over the gun issue, which has forced Sanders to explain some previous votes against gun regulation and led to O'Malley saying Clinton has "been on three sides" of the issue, quickly turned back into a debate over Wall Street.

A question from Twitter asks why Clinton invoked 9/11 to justify Wall Street donations.

Clinton reinforced her position that she doesn't think Glass-Steagall "would get the job done."

Here's the quick and dirty on Glass-Steagall.

10:01 p.m EST: Sanders and Clinton Spar Over Wall Street

Clinton vows to reign in Wall Street. Here's her plan.

Sanders said Clinton's plan is "not good enough." He said the big banks need to be broken up.

He says the fact that she takes campaign contributions from Wall Street mean she won't be tough against the banks.

Clinton said Sanders is trying to "impugn my integrity." And that she represented New York during 9/11 and she spent a lot of time on Wall Street and insinuated that that is the reason they support her. She adds that reinstating Glass Steagall could help but more needs to be done.

Sanders said, "I respectfully disagree with you." He said the consolidation of "such incredible power and wealth," means the only answer that i know is break them up.

O'Malley, begging to get in, sided with Sanders. "Bernie's right," O'Malley said. "We need to reinstate a modern version of Glass-Steagall."

Clinton also touted the volume of small dollar donors. Here's a graph that compares her small donations to the rest of the field.

9:48 p.m. EST: Immigration Quickly Turns To Debate Over Minimum Wage

O'Malley defended immigration but what will likely garner more attention is calling Donald Trump and "immigrant bashing carnival barker."

Trump predictably responded on Twitter:

Hillary and Sanders are not doing well, but what is the failed former Mayor of Baltimore doing on that stage? O'Malley is a clown. — Donald J. Trump (@realDonaldTrump) November 15, 2015

Clinton says the U.S. should make it possible for undocumented immigrants "to come out of the shadows." The audience loves this answer!

Remember that the Republican presidential candidates engaged in a bitter back-and-forth over immigration this past week, arguing over who is - and has been - the toughest on the issue. And Donald Trump called for a "humane" police force to deport all 11 million undocumented immigrants.

Sanders is asked about his position that immigration is tied to wages. he doesn't talk about immigration but says that "over the next few years" the minimum wage needs to be $15/hour.

Clinton says she supports a $12 minimum of a wage because she said it's "the highest historical" minimum wage."

Min wage is tricky issue for Hillary. If she endorses $15/hr she'll regret it in the general election. She goes with $12/hr as starting pt — Doug Adams (@DougNBC) November 15, 2015

O'Malley knocks Clinton, saying "we need to stop taking advice from economists on Wall Street."

9:37 p.m.EST: Now On To Domestic Policy

After the first break, the debate moderator moves on from terrorism and right into domestic policy, specifically debt-free college.

O'Malley said debt-free college can be paid by increasing the income tax on the wealthy and increase the capital gains tax.

Sanders is asked how to pay for an expansion of Social Security and free college and other social programs.

He says the wealthy and corporations will pay although he's not sure how much yet. He says it won't be as high as the 90 percent tax rate under the Eisenhower administration. And the self-described Democratic socialist tells the first joke of the night: "I'm no socialist compared to Eisenhower."

What is it with everyone loving up on Ike lately? Trump, now Bernie... https://t.co/AFPE0Ucy7i — Ali Vitali (@alivitali) November 15, 2015

O'Malley interjects and reminds that under Reagan, the highest marginal rate was at 70 percent.

9:29 p.m. EST: Refugees. Should The U.S. Accept Them?

Sanders said the U.S. should take "it's responsibility" to do its part but doesn't know how many refugees the should be accepted.

O'Malley said he supports taking in 65,000 refugees.

Clinton said she supports accepting refugees but screening them is the most important component.

9:24 p.m. EST: Will You Say "Radical Islam?"

It's not particularly helpful to use the term "radical Islam," Clinton said. She invokes President George W. Bush who said after 9/11 that Islam is a peaceful religion.

Sanders said the term is not what's important.

O'Malley said "radical jihadis" is "calling it what it is." But added that ISIS is "perverting" an honorable religion.

9:14:p.m. EST: Clinton's Iraq War Vote Criticized

Sanders went there early. He targets Clinton by saying the "disastrous invasion of Iraq has unraveled the region." (Clinton voted for the invasion of Iraq in 2003.)

"It's the worst foreign policy blunders in American history," Sanders said.

In a response, Clinton says the invasion of Iraq "was a mistake."

I think we have a disagreement," Sanders said. That disagreement he says, is that regime change and "invasions" have "unintended consequences."

9:08 p.m. EST: Clinton Asked To If She Is Responsible As Former Secretary of State:

Clinton is asked if the current administration, including Clinton as secretary of State, has failed in the fight against terrorism.

First, Clinton deflects and says the fight against ISIS cannot be an American fight. She says the U.S. should be "supportive" and American leadership is "essential."

When pressed, she separates herself from Obama saying she supported arming rebels in Syria.

O'Malley says he "disagrees" with Clinton because it IS America's fight. He says the great failure is intelligence on the ground.

Sanders says climate change is "directly related" to the growth of terrorism, but adds that terrorism is a major

9:00 p.m. EST: Opening statements:

Sen. Sanders' opening state called for the need to "rid" the planet of ISIS. But he immediately, however, turns to his strength, the economy where he talks about the political revolution.

Sen. Clinton, with the most foreign policy experience, says this election is about "choosing our next commander-in-chief" and what needs to be done "against the scourge of terrorism."

Gov. O'Malley's opening statement focuses on the "new face of conflict and warfare," saying "fresh approaches" are necessary - a knock against Clinton.
