President Trump on Wednesday morning attacked Sen. Richard Blumenthal (D-Conn.), calling for him to face an investigation over a 2010 campaign controversy about his military service.

Trump took to Twitter to slam Blumenthal shortly after the senator appeared on morning cable news shows to criticize Trump for firing FBI Director Jamed Comey, warning of a “looming constitutional crisis.”

“Watching Senator Richard Blumenthal speak of Comey is a joke. ‘Richie’ devised one of the greatest military frauds in U.S. history,” Trump wrote in a series of tweets.

“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.”

Trump was referring to a controversy in Blumenthal’s 2010 Senate campaign in which he admitted misspeaking about his military service.

Blumenthal held a press conference during the campaign to clarify that he had said he served “in” the Vietnam War when he meant to say he served “during” the war, as a reservist and not overseas.

Trump attacked Blumenthal earlier this year over the 2010 controversy, during debate about then-Supreme Court nominee Neil Gorsuch, accusing the senator of a “long-term lie.”
