Just in time for the November book, NBC is turning to Donald Trump to help goose SNL's ratings.

The network that pulled the plug on Trump's Celebrity Apprentice is bringing The Donald on board for SNL.

Trump will host the show on November 7th. 

But before Trump heads to SNL, he will be trying his hand at live Tweeting the Democratic Debate tonight. 

You know....because soooooo many of you requested him to do so.
