White House press Secretary Stephanie Grisham lashed out at Stanford law professor Pamela Karlan for mentioning Donald Trump’s son, Barron, during a Wednesday impeachment hearing, calling the remark “classless.”

Karlan – while explaining the president’s rights under Article 2 of the Constitution during the House Judiciary hearing – quipped that Trump can name his son Barron, but can’t give him a noble title.

“Contrary to what President Trump has said, Article 2 does not give him the power to do anything he wants, and I’ll just give you one example that shows you the difference between him and a king, which is, 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,” she said.

This remark, which prompted laughter in the room, was met with criticism from the White House, Trump’s reelection campaign and other Republicans.

“Classless move by a Democratic ‘witness,'” tweeted Grisham.

“Prof Karlan uses a teenage boy who has nothing to do with this joke of a hearing (and deserves privacy) as a punchline. And what’s worse, it’s met by laughter in the hearing room,” she added.

Classless move by a Democratic “witness”. Prof Karlan uses a teenage boy who has nothing to do with this joke of a hearing (and deserves privacy) as a punchline. And what’s worse, it’s met by laughter in the hearing room. What is being done to this country is no laughing matter.

Trump’s reelection campaign questioned why it has been scrutinized for its criticism of Democratic presidential candidate and former Vice President Joe Biden’s adult son Hunter, but that Barron could be mentioned.

“So Hunter Biden is off limits, but 13 year old Barron Trump is not? This gets more unreal by the minute!” the campaign wrote.

But it was clear Karlan wasn’t attacking Barron, just using his name to make a point:

Folks, if you seriously believe Prof. Pamela Karlan was attacking Barron Trump with that line, you need to take an aspirin and go to sleep for the night. Try again tomorrow.#ImpeachmentHearings

lol you fucking idiots

She said: Trump "can name his son Barron, but he can't make him a baron."

That's not an attack on Barron, nor a smear on the president. https://t.co/gUUEhzlZwR

She literally said that because he's not a king, he can name his son Barron, but not make him a baron.

These people are scraping for excuses. https://t.co/q8YIfSusgS

The right wing Twitterati are already shrieking that this is some horrible attack on Barron Trump. It's not, in any way. But now they've got their talking point for the next day. By this time tomorrow, nobody will remember it was said. https://t.co/Qs9dGKCHBU
