Liberal NY Times columnist: Trump 'was obviously mentally ill the moment he took office

Paul Krugman — a well-known economist, liberal New York Times columnist and outspoken opponent of Republican President Donald Trump — called the new commander in chief "mentally ill."

"An American first: a president who was obviously mentally ill the moment he took office," Krugman tweeted Tuesday morning, accompanied by a link to a New York Times story saying Trump "used his first official meeting with congressional leaders on Monday to falsely claim that millions of unauthorized immigrants had robbed him of a popular vote majority."

Krugman added a "Thanks, Comey" quip to his tweet, presumably a criticism of FBI Director James Comey over his disclosure to Congress shortly before the election about the restart of the investigation into then-Democratic nominee Hillary Clinton's private email server.

This was far from Krugman's first salvo directed toward Trump.

In his Monday column for the Times, Krugman called Trump's inauguration speech "ghastly" and criticized him over the economy, health care and crime.

"No, the insecure egomaniac-in-chief will almost surely deny awkward truths, and berate the media for reporting them," Krugman wrote. "And — this is what worries me — it’s very likely that he’ll try to use his power to shoot the messengers."

Last month Krugman suggested that Trump would allow terrorists to attack the U.S. on purpose.
