"He’s not going to be able to handle them," Trump said during an interview on "Fox & Friends."

Trump's comments came on the heels of an interview over the weekend between left-wing Reps. Alexandria Ocasio-Cortez, D-N.Y.; Ilhan Omar, D-Minn.; Rashida Tlaib, D-Mich.; Ayanna Pressley, D-Mass.; and Vermont Sen Bernie Sanders, a self-declared democratic socialist. 

“Our first task, we've got to defeat the worst president in modern history in this country, and number two, we organize our people to make sure that Biden becomes the most progressive president since FDR,” Sanders said.
