Will Indiana Gov. Mike Pence be Donald Trump's running mate? 

Fox News correspondent Carl Cameron reported (above) moments ago that the speculation is "through the roof" that Pence will be the VP pick. 

Trump will make the official announcement at 11am tomorrow morning at Trump Tower.

Former House Speaker Newt Gingrich, believed to be one of the finalists for the spot, has been telling people that he believes "in his gut" it will be Pence. 

Cameron cautioned that although the tea leaves are pointing to Pence as the "imminent" selection, the Trump campaign is denying it. 

One thing we do know is that Greta will interview Donald Trump on On the Record, tonight at 7:00 ET on Fox News Channel. 

PLUS... Newt Gingrich will talk to Sean Hannity at 10:00 ET tonight.
