Self-described “ very stable genius ” Donald Trump on Tuesday took aim at two of his most prominent critics in Congress — Reps. Alexandria Ocasio-Cortez (D-N.Y.) and Jasmine Crockett (D-Texas) ― with a demand that they take IQ tests.

Trump mocked AOC and Jasmine Crockett as “very low IQ" and challenged them to an IQ test before boarding Marine One on Tuesday afternoon.

Boasting that he had “aced” an intelligence test, the president said, “Now it’s time for them to take a test.”
