Al Sharpton Calls Out USA Basketball, Says Separate Digs Just Ain't American

Al Sharpton says it's downright UN-AMERICAN for the USA Hoops squad to get luxury treatment in Rio ... saying they should show some unity and rough it with the rest of the Olympic athletes.

If you didn't know ... the men and women's hoops teams got HOOKED UP in Brazil ... staying aboard a sick luxury liner while the other USA athletes get the freshman dorm experience in Olympic Village.

We got Sharpton out in NYC and asked about the accommodation inequality ... which he said is not only unfair ... but goes against everything the red, white and blue stands for.

It's worth noting ... the USA men's hoops team hasn't stayed in Olympic Village since the '88 games ... with the crew staying in hotels since the pros brought their celebrity status to the mix in '92.

Still though ... Sharpton's fired up. And that's always fun to see. Check it out.
