Schwarzenegger and Trump are each executive producers of the show, but they have exchanged criticisms in recent weeks.
Trump has slammed Schwarzenegger on Twitter for not delivering the same ratings as he did for the show.

“If they would run this by the Justice Department and Homeland Security, and had the lawyers really study and focus on it and give it some time to do it the right way.”
He said that the administration was “hasty” in issuing it.
