Sen. Jeff Flake, R-Ariz., on Monday pushed back on comments made by President Trump, rejecting Trump’s notion that those who did not applaud at his inaugural State of the Union speech last week were "un-American" and "treasonous.”

“You don't have to always agree with those on the other side of the aisle, but all members of Congress love their country, and none are treasonous,” Flake tweeted Monday evening, as he shared an article with Trump’s full comments.

Trump’s remarks were made in Ohio earlier Monday as he recounted that Democratic lawmakers were silent when he touted low unemployment among African Americans and Hispanic.

"You're up there and you have half the room going totally crazy wild. They loved everything, they want to do something great for our country," Trump said. "And you have the other side, even on positive news, really positive news like that, they were like death. And un-American, un-American."

"Somebody said treasonous. I mean, yeah, I guess why not,” he added. “Can we call that treason? Why not. They certainly didn't seem to love our country very much."

Flake has often been critical of Trump and the two have sparred previously, especially after Flake published a book, Conscience of a Conservative, that criticized Republicans who backed Trump.

Flake announced late last year that he would not be running for re-election in 2018. He served in the House for seven terms and was elected to the Senate in 2012.
