Highlights from the final presidential debate before Election Day.
President Donald Trump and former Vice President Joe Biden, the Democratic nominee, faced off in the final presidential debate of the 2020 election cycle from Belmont University in Nashville on Thursday night, marking the candidates’ last chance to pitch themselves to tens of millions of voters in primetime before Nov. 3.
The stakes were high: Trump needed to make his case as polls show him trailing nationally and in several battleground states key to his reelection hopes. At the same time, Biden had a platform to solidify his lead and avoid any major mistakes with Election Day just 12 days away.
Biden spent the week hunkered down in Wilmington, Delaware, to prepare -- what he's done before other debates -- while Trump had seemingly done less to prepare, telling reporters on Wednesday, "I do prep, I do prep," without elaborating. Earlier this week Trump said that answering journalists' questions is the best kind of preparation.
Thursday's debate was supposed to be the candidates' third matchup but is instead the second of only two presidential debates this election. Trump refused to participate in the second debate when it was moved to a virtual format following his COVID-19 diagnosis. The candidates ultimately participated in dueling town halls instead.

In the wake of that canceled second showdown and a chaotic first debate before it, the Commission on Presidential Debates announced earlier this week it would mute candidates’ microphones at certain points Thursday to avoid interruptions and “maintain order.”
Trump and Biden will now have two minutes each of uninterrupted time to speak at the beginning of each 15-minute segment, of which there are six, in the 90-minute debate.
After the first four minutes of each segment, both of their microphones will go live for an “open-discussion portion,” the commission co-chair said. The moderator will not have control of the candidates' mics at any point. Those will instead be controlled by event production staff.
ABC News Chief Congressional Correspondent Mary Bruce said on ABC News Live Prime ahead of the debate, “Just because your microphone is down, doesn't mean that you necessarily will stop talking.”
Trump has attacked the integrity of the debate commission and its chosen moderators in recent weeks, deeming it all "crazy" and the new mic rule "very unfair” -- but sources have told ABC News Chief White House Correspondent Jonathan Karl that some advisers think muting the mics will actually help the president.
Biden, meanwhile, has called the muting of mics "a good idea" and said he’s expecting Trump to fire off personal attacks during their final showdown.
ABC News Chief Anchor George Stephanopoulos said the big question for Biden, who leads in nationwide polls, is whether he can close the deal with voters from Nashville. For Trump, it's how will he adjusts his performance after the "disastrous" first debate more than three weeks ago.
"Even the president's own aides called his blustering performance a self-inflicted wound," Stephanopoulos said.

To win the presidency, candidates have to hit the magic number of 270 electoral votes. The Electoral College comprises a total of 538 members, with each state getting a total number of electoral votes equal to its congressional delegation and three additional electoral votes for District of Columbia.
American foreign policy for over half a century was defined by its bipartisan nature, symbolized in the old adage that politics stopped at the water's edge.
But in recent years, foreign policy has become as politically charged as virtually everything else in American life, and when voters mail in their ballots or go to the polls, they'll face a stark difference between the Republican and Democratic nominee and their views of the world and the United States' place in it.
Trump vs. Biden on the issues: Foreign policy
Ahead of Thursday's debate, the Trump campaign made an eleventh-hour demand that the questions focus on foreign policy, as opposed to the topics chosen by the moderator, though the campaigns agreed months ago to allowing the moderator to choose the debate topics.
