Hillary Clinton is home in Chappaqua, New York, today where she's preparing for Monday night's debate against Donald Trump. 

Clinton is off the campaign trail today and has not commented on Wednesday night's riots in Charlotte, North Carolina. 

Fox News correspondent Jennifer Griffin brought us some details about the debate prep, where one mystery remains: who is playing the role of Trump?

Griffin said the campaign refuses to reveal who it is, but confirmed it is not Al Franken. The campaign said it's preparing for two different Trumps: one who is aggressive and angry and another that's more "genteel."

Griffin said the campaign is hoping that NBC News' Lester Holt will speak up if Trump makes a false statement.

"They say they hope the moderators will fact-check the candidates in real-time during the debate," Griffin explained.

Holt will moderate Monday's forum, followed by ABC's Martha Raddatz and CNN's Anderson Cooper in the second debate and Fox News host Chris Wallace in the third debate.

Meantime, Trump expressed the opposite this morning on Fox & Friends, cautioning Holt against fact-checking.

"I mean, you’re debating somebody and if she makes a mistake or I make a mistake, I’ll, you know, we’ll take each other on. But I certainly don’t think you want Candy Crowley again," he said. 

Crowley made a controversial correction of Mitt Romney during a debate in 2012 after the GOP candidate alleged that President Obama had not referred to Benghazi as a terrorist attack. 

What do you think? Should the moderators call out the candidates during the debate?
