Presidential debate mute button gets starring role in "SNL" cold open

"Saturday Night Live" sent up Friday's presidential debate with plenty of microphone mute button jokes, as Alec Baldwin and Jim Carrey returned to duel as President Trump and Joe Biden in the latest cold open.

Highlights: Maya Rudolph as the moderator, NBC's Kristen Welker, noted, "Tonight, we have a mute button, because it was that or tranquilizer darts and the President has a very high tolerance for those after his COVD treatment." And Kate McKinnon, spoofing President Trump's lawyer Rudy Giuliani over a scene in the new "Borat" movie, exclaimed: "It's not what it looks like! My microphone was stuck."

• Singer Adele hosted "SNL" and H.E.R. was the musical guest.
