Trump has generally refrained from criticizing the retired neurosurgeon, who is closing in on Trump’s lead in some polls.


But in an interview on ABC’s “Good Morning America” on Wednesday, Trump said he would end his cease fire with Carson if the latter continued to gain in the polls.

“Probably. At some point, yes, which I actually look forward to doing," Trump said.

He said if Carson weren’t “so nice to me,” he wouldn’t be able to restrain himself.

Trump also said the retired neurosurgeon is not qualified to negotiate with foreign powers.

“Ben is a doctor,” Trump said. “That’s what he’s been doing. The question is, ‘Is he capable of negotiating with China, Russia and Iran?’ And there’s a lot of things that have to do with capacity and experience.”

Trump has been goading Carson into taking the first shot as the battle for the Republican presidential nomination heats up.

He said on Sunday he was “all set to go wild” after Carson questioned his faith but refrained after Carson apologized.

In an interview Tuesday with The Hill, Trump refrained from criticizing Carson, responding to a question about whether his rival is qualified to be president by saying, “I don’t want to comment on that now.”
