"Nobody wants me to talk about your other senator, who is weak on border [security], weak on crime, so I won't talk about him,” Trump said during his Phoenix rally.

On Wednesday, Trump attacked Flake more directly, saying he was "not a fan" of the Arizona senator, whom Trump called "weak on crime & border."

During the interview, Flake defended his record, adding that it was nice to see the president go down to the border and talk about what is going on there.

The Arizona Republican said he was pleased to work with the president on certain issues, pointing to the appointment of a Supreme Court justice. He also said Trump appointed a great national security team.

"So for my part, I'll continue to support the President, work with him when I think he's right, and challenge him when I think he is going in the wrong direction," Flake said.

When asked if he was worried about Trump endorsing one of his primary opponents, Flake brushed off concern. He said Trump will do what he wants to do.

Trump had previously tweeted praise for Kelli Ward, a Republican who is challenging Flake from the right in the GOP Senate primary next year.

"For me I just focused on one, my day job, and two, building a winning campaign and so I can't control what goes on with the other side," Flake said.

"But all I know is I'll have a strong campaign, and we knew all along we would have a challenging environment in Arizona. It's always that way, I've had tough primaries, I've had tough general elections."
