Conservative activist Ben Shapiro criticized Republican Arizona Sen.Jeff Flake in a scathing series of tweets Tuesday over his supposed reasons for not seeking re-election.

Flake had announced earlier that he would not seek re-election in 2018, and blamed the "flagrant disregard of truth" of the Trump age.

"Flake blaming his fall on Trump and the supposed inability of the base to support good people is disingenuous and cynical," Shapiro tweeted.

"Flake was deeply unpopular for years and was going to lose," he added. "Not because of Trump. Because he broke faith with his base."

"Blaming Trump and Trump voters is a way of playing hero while quitting because he was going to lose," he continued.

"The media will eat it up because anyone who badmouths Trump (and I agree with many Flake critiques) becomes a tragic hero," he added.

"Trump is happy to play into that story because it makes him look powerful," he continued. "Flake wants to play tragic hero. Media love the conflict."

So, in the end, this is cynical politics, as always, and sheer BS generally. Trump is not the party or the future of conservatism. (6/) — Ben Shapiro (@benshapiro) October 24, 2017

He is the president and a vehicle for the base's anger and desire to stop Democrats. Good people can still be elected. (END) — Ben Shapiro (@benshapiro) October 24, 2017

"He is the president and a vehicle for the base's anger and desire to stop Democrats," Shapiro concluded. "Good people can still be elected."

Flake had been a vocal critic of Trump, and cited him as a main reason why he couldn't maintain his office.

"We must never meekly accept the daily sundering of our country," Flake said Tuesday on the Senate floor, "the personal attacks, the threats against principles, freedoms, and institutions, the flagrant disregard for truth or decency, the reckless provocations, most often for the pettiest and most personal reasons, reasons having nothing whatsoever to do with the fortunes of the people that we have all been elected to serve."
