ARIZONA GOP SENATOR JEFF FLAKE: I can’t support Donald Trump at this point.

“It’s uncomfortable not having endorsed the Republican nominee, I have to say, but I can’t at this point,” Mr. Flake said on MSNBC’s “Morning Joe.”

“I hope to be able to support the nominee. I certainly can’t right now,” Mr. Flake said.

Even Republican leaders who have said they’ll support Mr. Trump, such as House Speaker Paul D. Ryan and Senate Majority Leader Mitch McConnell, have distanced themselves from Mr. Trump’s attacks on Judge Gonzalo Curiel, who is overseeing one of the cases alleging fraud against Trump University.

Mr. Trump has said Judge Curiel has a conflict of interest because he has Mexican ancestry and Mr. Trump has pledged to build a wall along the U.S.-Mexico border.

“His statements this week on the judge — that’s a new level,” Mr. Flake said. “Because it’s not just … ill-informed or ignorant statements, but they suggest that when he’s president, you know, after November, that … perhaps he ought to go after that judge. That’s a whole new level. So that’s — it’s very disturbing.”

To be fair, it’s nothing new under the Obama Administration, but it might be a whole new level for a Republican.
