When it comes to the prospect of Republicans not supporting his candidacy as retaliation for Donald Trump not supporting theirs, the GOP nominee says he is "not concerned about anything."

Trump sent shockwaves through the Republican establishment on Tuesday with his refusal in a Washington Post interview to endorse House Speaker Paul Ryan in his primary next week in Wisconsin, as well as voicing similar sentiments for incumbent Sens. John McCain, of Arizona, and Kelly Ayotte, of New Hampshire.


"I think we’re gonna do really well. I was, you know, very forthright when I said, when I made certain statements," Trump told Florida CBS affiliate WPEC on Wednesday. "And you know, I’m happy with them. We’ll see what happens. I think we’re going to do very well."

Running mate Mike Pence said Wednesday that he was endorsing Ryan, adding that Trump had privately encouraged him to do so.

Asked whether he would agree with Republican allies who say his recent attacks on targets other than Hillary Clinton are misguided, Trump responded, "Well, I think that’s probably right. More focus on Hillary Clinton."

"She’s a disaster," Trump added. "So, we’re going to focus more on Hillary Clinton. Absolutely."
