Derek Jeter on Golfing with Obama ... 'We Talked About Some Things'

What happens when President Barack Obama goes golfing with Derek Jeter? According to #2 ... "We talked about some things."

The NY Yankees legend was doing a Q&A at Steiner Sports in NYC on Saturday when he was asked about his Nov. 22nd golf excursion with the leader of the free world in Las Vegas.

"I heard that he wanted to play ... and I'm not good at all ... so I was extremely nervous," Jeter revealed.

FYI -- Jeter and Obama's foursome included Las Vegas Sun newspaper owner Brian Greenspun and campaign supporter Stephen Cloobeck.

Question is ... what did Jeter talk to the President about? Healthcare? ISIS? Ferguson? A possible political run???

Jeter wouldn't say exactly ... but he did suggest he beat Obama's ass on the links.
