Jack Nicklaus endorses Donald Trump. CBS News

Presumptive GOP presidential nominee Donald Trump has received a few endorsements from golfers, other athletes and coaches this year, but he got his biggest one to date from Jack Nicklaus over the weekend. The Golden Bear went on CBS Sunday Morning to discuss a variety of things, most notably The Donald.

Trump's persona is of course ingrained in the golf world deeper than most. He owns Doral, where the Cadillac Championship is played, and just had Turnberry re-done which, presumably, will get another British Open in the future. He's even done deals with Jack Nicklaus in the past.

"I like what Donald has done," Nicklaus told CBS. "He's turning America upside-down. [He's] awakening the country. Is he as smooth and as politically correct as he should be? Probably not. But he'll learn. He's not stupid. He didn't get where he was being dumb. I like the guy. He's a good man. If he's the one that's on the ticket, then I'll be voting for him. "
