Sen. Richard Blumenthal said Wednesday that President Donald Trump’s decision to fire his FBI director could lead to possible impeachment proceedings in Congress.

“It may well produce another United States vs. Nixon on a subpoena that went to United States Supreme Court,” the Connecticut Democrat said on “Anderson Cooper 360.” “It may well produce impeachment proceedings, although we’re very far from that possibility.”

His comments come a day after Trump shocked Washington by firing FBI Director James Comey, acting on recommendations from Attorney General Jeff Sessions and Deputy Attorney General Rod Rosenstein.

Blumenthal has been quick to criticize the President in wake of the firing. On CNN’s “New Day,” Wednesday, he called Trump’s decision “a looming constitutional crisis.”

In response, Trump went after Blumenthal on Twitter.

“Watching Senator Richard Blumenthal speak of Comey is a joke,” the President wrote in three tweets. “‘Richie’ devised one of the greatest military frauds in U.S. history. For years, as a pol in Connecticut, Blumenthal would talk of his great bravery and conquests in Vietnam — except he was never there. When caught, he cried like a baby and begged for forgiveness … and now he is judge & jury. He should be the one who is investigated for his acts.”

Blumenthal admitted in 2010 to misrepresenting his military service after saying he had been “in” Vietnam. Blumenthal served in the Marine Reserves in Washington, not Vietnam. “I have misspoken about my service, and I regret that, and I take full responsibility,” Blumenthal said in 2010.
