One of Hillary Clinton’s biggest supporters throughout the election cycle, New York Times columnist and Nobel Prize winner Paul Krugman, is now claiming that FBI Director James Comey and Russian President Vladimir Putin “installed” Donald Trump.

Ever since it became clear that Trump would be the next President of the United States, Krugman has been lashing out in a big way on Twitter. His latest claims may be his most far fetched to date.

On Sunday, Krugman tweeted a screenshot of Trump stating that if you deducted the millions of people who voted illegally, he would have won the popular vote, in addition to winning the Electoral College. The tweet was a portion of a twitter rant by the President-elect regarding the recount efforts of the Green Party.

“So Comey and Putin installed a crazy, vindictive can't-handle-the-truth person in the White House. Scary,” Krugman tweeted with the screenshot.

Essentially, Krugman is implying that Trump is a crazy conspiracy theorist, while sharing the unhinged theory that the FBI is collaborating with the Russian government. Naturally, Twitter users, particularly other journalists, were quick to point out the hypocrisy.

This is not the first time since the election that Krugman made headlines for spouting crazy conspiracy theories about how the US Presidency was stolen from Clinton by Russia. It is not even the first time in the past week.

Last Tuesday, Krugman went into a twitter-storm rant about Russians hacking into the US voting systems.

In a thoughtful analysis for the Federalist, Daniel Payne wrote about the “damaged psyches of the left,” based on Krugman’s unhinged rant.

Payne notes that the economist is starting to “sound like a tinfoil-hat-wearing neighborhood crank."

“Krugman’s flip-flop—from a denigrator of ‘crazy conspiracy theories’ to an eager promoter of them—exposes perhaps just how fragile the political psyche of modern American liberalism is,” Payne wrote.

The article discussed how Clinton was all but ordained, and when it all came crashing down to hit smug progressive pundits, including Krugman, the reality was too much to accept.

“The election of Donald Trump—not merely an earthquake but an extinction-level asteroid event—brought it all crashing down. And you can see that in the behavior of Paul Krugman, a man who has been confronted with, and is struggling mightily to accept, the way the world is,” Payne said. “Really, this wake-up call has kind of been a long time coming: there are few columnists on the scene today more intellectually closed and pompous than Krugman, a fellow who once wrote about a particular policy debate, ‘I…have been right about everything.’ Even when you’re right about everything, you don’t write, ‘I have been right about everything.’ Unless you’re Paul Krugman, that is.”

Maybe next Krugman will accuse US President Barack Obama of also working with the Kremlin, since on Friday he stated in no uncertain terms that the election results “accurately reflect the will of the American people."
