Washington University in St. Louis will host the second of this year's three presidential debates on Sunday, Oct. 9, 2016. Here are important details known about the event so far.
DONALD TRUMP VS. HILLARY CLINTON
This rematch between Democratic presidential nominee Hillary Clinton and Republican nominee Donald Trump follows their first debate at Hofstra University on Long Island on Sept. 26. It set a record as the most-watched debate in history with an estimated 84 million viewers, according to Nielsen.
Libertarian nominee Gary Johnson (7.4 percent) and Green Party nominee Jill Stein (2.6 percent) did not meet the 15 percent national polling threshold they needed to make the cut.
The debate begins at 9 p.m. New York time and ends at 10:30 p.m.
It's a town hall format, with undecided voters asking half the questions. The rest will be posed by moderators Anderson Cooper of CNN and Martha Raddatz of ABC News.
The nonpartisan Commission on Presidential Debates oversees the event.
HOW THEY ARE PREPARING
Trump held a town hall in New Hampshire Thursday night — but scorned preparing for the debate.
"I said, 'Forget debate prep.' I mean, give me a break," said the GOP candidate, who mocked his Democratic rival for spending days getting ready. "She's resting. She wants to build up her energy for Sunday night. And you know what? That's fine. But the narrative is so foolish."
Clinton's preparation included an exhaustive five-hour session on Wednesday, The Washington Post reported. "Hillary did a lot of town-hall debates and a lot of town halls during the course of the primaries and into the general. She's very used to the format. She likes it," the Post quoted Clinton campaign manager John Podesta saying.
WHERE TO WATCH
The debate will be widely available on broadcast and cable networks, and on livestreams.
The school has hosted three previous presidential debates — in 1992, 2000 and 2004 — and the 2008 vice presidential debate between Joe Biden and Sarah Palin.
As many as 2,000 journalists could cover the debate from the scene, the St. Louis Post-Dispatch reported. That kind of turnout is "unprecedented," CPD leaders say.
Sixty thousand square feet of red carpet has been installed for the debate, the school says. Two hundred plush bears and 4,000 temporary tattoos are waiting to be given away in student debate swag, and an estimated 950 pounds of roasted turkey will be served via on-campus catering this weekend.
So far 2,682 students have registered to vote because of the debate, according to the university.
The third and final presidential debate will be held at the University of Nevada-Las Vegas on Wednesday, Oct. 19. Its moderator will be Fox News' Chris Wallace.
