Inside the Feud Between Donald Trump and Samuel L. Jackson

— -- Well, that escalated quickly.

When asked who was the better golfer, the "Pulp Fiction" star said, "Oh, I am, for sure. I don't cheat."

But Trump, 69, isn't budging, and even fired back at what Jackson originally said about him cheating.

"I don’t cheat at golf but @SamuelLJackson cheats—with his game he has no choice—and stop doing commercials!" he added today, followed by, "Don’t like @SamuelLJackson’s golf swing. Not athletic. I’ve won many club championships. Play him for charity!"
