Chris Christie Coaches Trump for Upcoming 'SNL' Appearance

Gov. Christie tells Donald Trump all he needs to know before he hosts SNL.

"Have fun," Christie said in an interview with ABC News' Jonathan Karl Thursday. "It’s a really good group of folks, it’s entertaining, and they make you comfortable."

Trump last hosted the show in 2004 during the first season of "The Apprentice." He hosts the comedy show this Saturday night.

"At least the way they did it with me, they make you comfortable and I felt really free and easy that night to just have a good time and be funny," Christie said. "So I hope [Trump] does the same because if he does, he’ll have a good time."

Christie also commented on the controversy surrounding Trump's appearance, with more than 500,000 people signing a petition asking Trump to be "dumped" from the show over his comments about immigrants.

"They have to make their decisions and live with their decisions," Christie said of NBC. "They're all adults over there, they could do whatever they want. Doesn’t matter if Donald is on 'SNL,' good for him. If he has a good time, even better for him."
