Donald Trump's campaign chairman said this morning that the "Never Trump" movement within the Republican Party is "nevermore" and there will be no challenge at next week's GOP Convention in Cleveland.

Paul Manafort said the party would have been "destroyed" if Trump had been denied the nomination through a "back-room deal."

In an RNC Rules Committee vote yesterday, a proposal to unbind the delegates and let them "vote their conscience" failed by a margin of 87-12, he said in a Fox and Friends interview.

"We crushed them. ... As far as I'm concerned, the 'Never Trump' movement is nevermore. It's gone," he said.

Trump was supposed to announce his VP choice today, but postponed it due to the Nice terror attack. Manafort said the announcement will come this weekend. 

He described Trump as "emotionally moved" by the latest terror massacre and felt it would be inappropriate to make a political speech. 

Manafort said Tim Tebow should not have been announced on the list of speakers for the convention. Tebow said last night that he was surprised to see his name on the list. 

"I just got back from the Philippines, and I wake up this morning to find out I'm speaking at the Republican National Convention," Tebow said in an Instagram video. "It’s amazing how fast rumors fly, and that’s exactly what it is -- a rumor.”
