Donald Trump criticized Joe Biden and Kamala Harris during Oval Office remarks on Tuesday, March 24, renewing past attacks on their intelligence. The comments came after the swearing-in of Homeland Security Secretary Markwayne Mullin, as Trump addressed topics including the conflict with Iran and border control. In a clip shared to X, he said, “Gonna give ’em IQ tests next week.” Earlier in 2024, he used similar language during an Arizona campaign stop, according to NBC News. Harris later told CBS Evening News she would take a cognitive test and urged Trump to do the same. She has also accused his administration of undermining checks and balances.
