Alec Baldwin has been tapped to play Donald Trump on the upcoming new season of "Saturday Night Live". The former "30 Rock" actor is booked after Taran Killam who usually impersonated the GOP presidential candidate left the show.

Baldwin will make his debut as the Republican politician during the premiere episode of "SNL" season 42 on October 1. Fresh off the first U.S. presidential debate, it's only fitting that Baldwin's Trump faces off Hillary Clinton who will be played by Kate McKinnon again.
