The top-ranking Senate Republican has made clear in multiple interviews over the course of the last two weeks that Donald Trump's comments about Indiana-born Judge Gonzalo Curiel being a "Mexican" are unacceptable.

But Mitch McConnell, in an interview with Bloomberg published Friday, went a step further, and would not categorically rule out revoking his endorsement of Trump as the GOP's presumptive presidential nominee.


“I'm not going to speculate about what he might say, or what I might do," McConnell told Bloomberg's Masters in Politics podcast. "But I think it's pretty clear and I've been pretty clear publicly about how I think he ought to change direction and I hope that's what we are going to see.”

McConnell, whose press tour for his latest book "The Long Game" has coincided with an all-out firestorm about Trump's remarks, said the reality TV star-turned-Republican-standard bearer needs someone on his ticket who can counterbalance his political green thumb.

“He needs someone highly experienced and very knowledgeable because it's pretty obvious he doesn't know a lot about the issues,” McConnell said. “You see that in the debates in which he's participated. It's why I have argued to him publicly and privately that he ought to use a script more often — there is nothing wrong with having prepared texts.”

Regardless, McConnell said he currently feels "comfortable supporting him" because "if he is in the White House he'll have to respond to the right-of-center world which elected him, and the things that we believe in."
