“You’ve got to pull your endorsements,” she said. "Please don’t make me or anyone at this table on television ... don’t make us the ones to tell you. You need to pull your endorsement. You need to do something strong. You need to lead. We’re begging you to lead.”

Brzezinski said Trump’s presidential campaign is damaging the businessman beyond politics.

“This is hurting his business,” she said. "Talk about ‘The Biggest Loser.' Isn’t that a show on NBC? He could end up being the biggest loser.

“He could lose this election huge, and his brand could be damaged forever. At this point, that’s where he’s going. We haven’t been wrong about him so far. So I wouldn’t mock that, Donald Trump.”

Brzezinski clashed over Trump with former Republican National Committee Chairman Michael Steele, who said the "Morning Joe" co-host already made up her mind to not give Trump a chance.

“I know a lot of Republicans who feel the same way because Donald Trump seems like he might not even be all right, if you know what I mean,” she added.

“Not everybody feels the way you feel,” Steele responded. "There are those who do actually support Donald Trump.

“The fact of the matter is, this is a fight for the White House this fall. And a lot of Republicans, myself included, are going to be in that fight through this fall."
