Comedians such as Stephen Colbert, Jimmy Kimmel and Jimmy Fallon have increasingly made headlines for their political monologues and jokes directed at none other than the president of the United States.

Trump said the hosts were “always anti-Trump,” and he brought up a 1934 “equal time” law that requires radio and network television stations to give equal opportunities for opposing political candidates to express their points of view.

It’s a Federal Communications Commission (FCC) rule that applies to politicians — and it isn’t often brought up.
