South Park's creators to back off Trump jokes

South Park's creators say they will stop making so much fun of United States President Donald Trump because he's doing a good enough job of it himself.

The animated sitcom features a Trump-like character, Herbert Garrison, as the 45th President.

But the show's creators Trey Parker and Matt Stone say they're going to back off the Trump jokes in the upcoming 21st season because, according to Parker, "satire has become reality" and he and his administration have become too hard to make fun of.

"They're already going out and doing the comedy," he told ABC Australia. "It's not something you can make fun of."

"In the last season of South Park we were really trying to make fun of what was going on but we couldn't keep up, and what was actually happening was much funnier than anything we could come up with.

"So we decided to kind of back off and let them do their comedy and we'll do ours."

Stone said he was finding it hard to take pleasure in the US political climate.

"People say to us all the time, 'Oh, you guys are getting all this good material,' like we're happy about some of this stuff that's happening," he said. "But I don't know if that's true. It doesn't feel that way."

It's not clear what will become of Herbert Garrison in future episodes of South Park. After being elected President in season 20, he used his newfound power to force people he disliked to perform sex acts on him.
