During a press conference on Wednesday, President Donald Trump said that he "did the country a great service" by "retiring" Arizona Sen. Jeff Flake (R) from his post.

Daily Mail reporter Francesca Chambers asked the president whose "fault" it was for the multiple retirements in Congress, as Trump had mentioned earlier in the presser that multiple lawmakers' retirements affected this year's midterms.

Flake, a prominent critic of Trump, announced last year that he wouldn't be seeking re-election, and House Speaker Paul Ryan (R-Wisc.), announced in April that he would also not be seeking re-election. In the case of Flake, many predicted he would have faced a difficult challenge in the Republican primary.

Trump replied that in the case of Flake, it was he who actually retired the moderate senator.

"It was me," he said. "Pure and simple. I retired him."

He said that he was "very proud" and that he "did the country a great service" by doing so.

"He is retired. I'd like to call it another word but we're gonna treat him with great respect," Trump added.

Flake, a frequent Trump critic, was the center of attention in September after he called for an FBI probe into then-Supreme Court nominee Brett Kavanaugh.

He had voted to send Kavanaugh's nomination to the full Senate, but then called for a one-week delay to allow the FBI to investigate the sexual misconduct claims against the nominee.

In a new op-ed, Flake wrote in the Washington Post that Republicans must move past the "cult" of Trump's personality.
