First Lady Melania Trump slammed a Democrat impeachment witness for invoking Barron Trump during the Wednesday impeachment hearing in an effort to attack the president. 

“A minor child deserves privacy and should be kept out of politics. Pamela Karlan, you should be ashamed of your very angry and obviously biased public pandering, and using a child to do it,” the first lady tweeted.

Stanford Law School professor and Appellate Attorney Pamela Karlan, one of the Democrats’ star witness during the House Judiciary Committee’s hearing, used President Trump’s son Barron as an example to show difference between the president’s position and that of a medieval king. 

“The Constitution says there can be no titles of nobility, so while the president can name his son ‘Barron’, he can’t make him a baron,” Karlan said in response to a question from Rep. Sheila Jackson Lee (D-Texas) during the hearing. 

Karlan’s remark drew sharp criticisms from Republican lawmakers, slamming her for making fun of the president’s youngest son, as children are traditionally off-limits. 

Democrats in the impeachment hearing laughed at the Karlen’s comparisons, sparking the ire from White House press secretary Stephanie Grisham.

“Classless move by a Democratic ‘witness,'” Grisham wrote on a tweet. “Professor Karlan uses a teenage boy who has nothing to do with this joke of a hearing (and deserves privacy) as a punchline.”

“What’s worse, it’s met by laughter in the hearing room,” she wrote. “What is being done to this country is no laughing matter.”

House Judiciary Committee member Rep. Matt Gaetz (R-Fla.) also vocally criticized Karlan for her remark, saying it does not lend “credibility” to her argument.

“When you invoke the president’s son’s name here, when you try to make a little joke out of referencing Barron Trump… it makes you look mean, it makes you look like you are attacking someone’s family: the minor child of the president of the United States.”

Gaetz also pointed out Karlan’s apparent bias, noting that she had appeared on an anti-Trump podcast, disparaged conservatives, and donated to Barack Obama, Hillary Clinton, and Elizabeth Warren.
