Watch live: Hillary Clinton, Donald Trump go into 2nd presidential debate amid scandal

ST. LOUIS, Oct. 9 (UPI) -- What a difference a day can make.

All eyes will be on Republican presidential nominee Donald Trump on Sunday night as he takes the stage for the first time since a shocking video was released of him describing in vulgar language his efforts to have sex with a married woman and "grabbing" other women by the genitals who permitted it because he's "a star."

The controversy has been widely condemned and caused several top Republicans to revoke their endorsements or call on Trump to drop out of the race.

Sunday's debate is the second between Trump and Democratic nominee Hillary Clinton, who is also on the hot seat after the anti-secrecy group WikiLeaks put out emails purported to be from her campaign chairman John Podesta. They include transcripts of paid speeches she gave to the banking industry, in one instance telling South American bankers she envisions a Western Hemisphere with "open trade and open borders."

Their first debate drew more than 84 million television viewers and millions more online, a record for presidential debate viewership.

Here's what you need to know for Sunday's presidential debate.

WHEN: The debate is scheduled to last 90 minutes without commercial interruption, though both the first presidential debate and the vice presidential debate ran long on time. It will begin at 9 p.m. Eastern.

WHERE: Washington University, a private university in St. Louis.

HOW TO WATCH: All the major broadcast networks, along with cable news networks will carry the debate live. It will also be streamed live on Facebook, Twitter and various YouTube channels. A link to one of the feeds can be found below and UPI will have full coverage and a video of the debate available shortly after its conclusion.

MODERATORS: Sunday's debate is the only one of the four debates put on by the Commission on Presidential Debates that will have two moderators. They are Anderson Cooper, anchor of CNN's AC 360, and Martha Raddatz, chief global affairs correspondent for ABC News.

FORMAT: Sunday's debate will be different than the first and third debates. It will follow the form of a town hall meeting, with the audience surrounding the candidates and undecided voters selected by the pollster Gallup being given the opportunity to ask questions of the candidates. It's expected about half the questions will come from the audience and half from the moderators. Candidates will have two minutes to respond to each question, followed by one minute for the moderators to facilitate further discussion of the topic.
