Top Democrats accuse Donald Trump of waging a campaign against free expression after he celebrated ABC's suspension of talk show host Jimmy Kimmel. Civil-liberties groups warn the moves echo McCarthy-era censorship.

"What is happening to people who reject the canonization of Charlie Kirk is a tragedy and a disgrace," one professor said.

"Good riddance, Kimmel, you disgusting scumbag."
