Perhaps the comedians best suited to fight President Donald Trump are the ones who speak his language of crass insult most fluently. The season premiere of "South Park," which aired July 23, depicted Trump in crude caricature - involved in a gay sexual affair with Satan and embarrassed over his minuscule genitalia.

The Comedy Central show certainly is a key asset for Paramount. But it has emerged this summer as one of the most scathing critics of President Trump on US television, raising concerns about whether Paramount has the stomach for the political headaches that could follow.
