Some men just know how to introduce themselves.

Contained in Sean Sullivan's and Philip Rucker's great write-up of Donald Trump's visit to Capitol Hill on Thursday is this gem, courtesy of one of the Senate Republicans most reluctant to support the presumptive Republican nominee for president -- Sen. Jeff Flake:

When Flake stood up and introduced himself, Trump told him, “You’ve been very critical of me.”

“Yes, I’m the other senator from Arizona — the one who didn’t get captured — and I want to talk to you about statements like that,” Flake responded, according to two Republican officials.

Flake was referring to one of Trump's earliest campaign controversies, when he suggested that Flake's fellow Republican senator from Arizona, John McCain, wasn't a war hero because Trump prefers "people who weren't captured."

Flake has confirmed the comment.

It's hardly the first time Flake has tossed some shade in Trump's direction. Last month, he suggested his colleagues withhold their support for the candidate. He has also been open about how Trump might hurt downballot Republicans -- like McCain, who faces a tougher-than-usual reelection race in 2016. "I'm grateful that I'm not running this year," Flake said.

Flake has also called Trump's comments about a judge of Mexican heritage "simply boorish."
