Secret Service ain't gonna like this ... NBA player Drew Gooden says he's been to the White House to play basketball ... but not with Obama ... claiming to TMZ Sports HE SNUCK on B.O.'s home court and hooped out.
Drew plays for the Washington Wizards ... so when we got him out in L.A. we wanted to know if he's ever gotten to ball with the Prez ... who's of course a rabid hoops fan.
That's when Drew laid it on us ... saying he's never run with Obama .
