President Donald Trump coined a new nickname for Connecticut Democratic Sen. Richard Blumenthal in reference to his past lies about serving in the Vietnam War during a Monday impromptu press conference at the White House.

“Look at Blumenthal. Lied about Vietnam for 15 years, and he said he was a war hero,” Trump said. “He said he was Da Nang Richard.”

The president continued, “He says we need honesty and we need integrity. This guy lied. When he was the attorney general of Connecticut, he lied. I do not mean a little bit.”

Trump appeared to have referenced Blumenthal’s question to Judge Brett Kavanaugh during a hearing on decades-old sexual allegations against the Supreme Court nominee. “The core of why we are here today really is credibility,” the Senator said in his opening remarks.

Trump tweeted about Blumenthal’s past lie over the weekend.
