President Trump on Monday said Sen. Kamala Harris’ frequent bursts of laughter at serious questions suggests “there’s something wrong” with the Democratic vice presidential candidate.

Trump mocked Harris’ “60 Minutes” interview, broadcast Sunday, during a campaign rally in Allentown, Pa.

“Did you see [Democratic presidential candidate Joe Biden’s] performance on that show? The only thing almost as bad was Kamala, with the laugh. ‘Haha, that’s so funny. Hahaha.’ She kept laughing. I said, ‘Is there something wrong with her, too?’” Trump quipped.

“She will not be the first woman president, you can’t let that happen. I said, ‘Is there something wrong with her?’ She kept laughing at very, you know, serious questions.”

Harris (D-Calif.) laughed off journalist Norah O’Donnell’s question during the “60 Minutes” interview about being rated the “most liberal” senator by GovTrack. She laughed again when she called herself someone who likes hip-hop.

O’Donnell pressed Harris on whether she brings a “socialist or progressive perspective” to the Democratic ticket.

“No, no,” Harris replied, immediately laughing.

“It is the perspective of — of a woman who grew up — a black child in America, who was also a prosecutor, who also has a mother who arrived here at the age of 19 from India. Who also, you know, l — likes hip-hop. Like, what do you wanna know?” she continued, repeatedly laughing.

Trump and his allies attack Harris as someone who’s an unprincipled “phony.”

Trump frequently says Biden, 77, is senile. He nicknamed the candidate “Sleepy Joe” and told the Allentown audience that although some polls have Biden at 50 percent, the former vice president is actually “50 percent” in the head.
