Conservative lawyer George Conway lambasted President Donald Trump Monday on Twitter, calling him a “malignant narcissist” in one of multiple tweets.

Conway, the husband of White House counselor Kellyanne Conwayhas been one of Trump’s fiercest critics on Twitter, mocking his brashness and calling out his lies at nearly every turn on the platform.

“You are a malignant narcissist—a person with both narcissistic and antisocial personality disorders—you couldn’t view it that way,” Conway wrote in response to a Trump tweet about the Russia investigation, which he claimed again was a “hoax” and a “witch hunt” and that Democrats and intelligence agencies were “spying” on his 2016 campaign. “Instead of complying with your oath of office, and instead of taking stock of what was in the best interests of the nation whose Constitution and laws you swore to uphold, you viewed the matter purely in terms of your own ego: You viewed the investigation as casting doubt on what you perceive as your great election victory (in which your opponent garnered nearly three million more votes than you did.”


After blasting Trump for his extreme arrogance and reminding him that Hillary Clinton won the popular vote in 2016 by a large margin, Conway slammed the president for lying about his attempts to thwart special counsel Robert Mueller‘s probe and obstruct justice.

“You took multiple steps to obstruct, and repeatedly lied about, the investigation from the outset. Even today, despite the well-founded assessments of the intelligence community, and despite the damning evidence laid out in the Mueller report, you refuse to take what the Russians did seriously,” Conway continued.

Conway also accused Trump of committing “statutory crimes” and of putting his own interests above those of the country.

George Conway’s criticism of Trump has reportedly strained his relationship with his wife, who is one of the president’s closest advisers. The attorney has pointed out numerous times why Trump’s actions and general behavior is unconstitutional.
