Sen. Richard Blumenthal lectured embattled Supreme Court nominee Brett Kavanaugh on the importance of not telling even a single lie, but now the Connecticut Democrat's own difficult history with the truth is coming back to haunt him.

“Falsus in uno, falsus in omnibus. It means 'False in one thing, false in everything,'" Blumenthal said to Kavanaugh during a Senate Judiciary Committee hearing.

President Trump and Republican lawmakers, however, noted the hypocrisy of those words coming from Blumenthal, who has been criticized for inflating his military service during the Vietnam War.

Blumenthal has implied in the past that he served on the ground in Vietnam, although he reportedly obtained at least five military deferments between 1965 and 1970. He eventually served in the U.S. Marine Corps Reserve, but did not deploy to Vietnam.

“You have the great Vietnam War hero—who didn’t go to Vietnam—Blumenthal,” Trump said at a rally Monday evening. “How about Blumenthal? We call him ‘Da Nang Blumenthal.”

On "Outnumbered" Tuesday, Charles Hurt said all politicians prevaricate to some degree, but it's another thing altogether to "steal valor."

"Ever since that story came out, I've never looked at Richard Blumenthal again and not thought of that story," Hurt said. "You're a liar. And you lied about all those things."

He added that Trump again proved himself to be a master with nicknames by coining "Da Nang Blumenthal."

"I do love when the president throws around 'lying' stuff, as someone who does have trouble with the truth himself," Jessica Tarlov countered, noting that Trump also received five draft deferments during the Vietnam War, including one medical deferment for bone spurs in his foot.

Melissa Francis said the problem that many people have with Blumenthal -- and with many lawmakers in Washington -- is the complete hypocrisy.

"So you stand there and you point the finger at someone else for something you yourself did?" Francis said.
