MSNBC's Mika Brzezinski brought her cat to the "Morning Joe" studios to mock J.D. Vance's past comments about "childless cat ladies."

The Ohio senator and freshly minted Republican presidential nominee once dismissed Vice President Kamala Harris – now the likely Democratic presidential nominee — as a legitimate stakeholder in the nation she hopes to lead because, he argued, she did not have any children of her own and instead kept cats as pets.

"We're effectively run in this country via the Democrats, via our corporate oligarchs, by childless cat ladies who are miserable at their own lives and the choices they've made," Vance told then-Fox News host Tucker Carlson in 2021.....

After that clip aired, the show's producers cut to Brzezinski sitting at her desk and stroking a cat on her lap.

"I've just got to say," she said dryly as others on set laughed, "My kids are older. Does that make me childless? I want to qualify."....

"If people are saying, well, this is just because Joe was a member [of Congress] so long ago, I keep talking about the guy in Iowa," Scarborough added. "What's his name? Steve King, yeah, they got rid of him in 2015 or 2016 for saying things then that would have put him, like, at the Republican National Convention in primetime giving speeches. I'm not joking, like, I'm not joking. That is how quickly the Republican Party has gone. They keep losing elections. Just run as a Republican, a traditional Republican. You'd be shocked at what might happen on the national level."
