"Upon scheduling a trip to Arizona, Governor Pence's office reached out to John McCain to request a meeting," Lorna Romero, a spokeswoman for McCain's campaign, told The Hill.

"John McCain was happy to welcome Governor Pence to Phoenix, and they enjoyed a very friendly meeting, during which they discussed a variety of issues.”

The Indiana governor was in Arizona Tuesday for two campaign events as McCain and Trump traded barbs.

The Arizona senator issued a scathing statement blasting Trump for criticizing the parents of a fallen Muslim U.S. soldier on Monday.

Trump responded on Tuesday by declining to endorse McCain's reelection campaign in an interview with The Washington Post.

“I haven’t endorsed John McCain,” Trump said. “I’ve never been there with John McCain because I’ve always felt that he should have done a much better job for the vets.

“He has not done a good job for the vets and I’ve always felt that he should have done a much better job for the vets. So I’ve always had a difficult time with John for that reason, because our vets are not being treated properly. They’re not being treated fairly.”
