Source: Trump-backer Mark Burnett warns staff against leaking "Apprentice" tapes

Burnett “is pro-Trump and has made clear to his teams that he will sue anyone who leaks,” the person said.

Another top Burnett star, the pro-Clinton billionaire and Trump foe Mark Cuban, defended the producer’s right to stay out of the fray.

“Burnett can make his own decisions,” billionaire Mark Cuban, who is also an investor on ABC’s reality series Shark Tank, told BuzzFeed News.

Burnett has remained publicly neutral and studiously avoided questions about his role in the presidential campaign.
