NBA union head Chris Paul challenges Trump's manhood in Twitter blast over black athlete attacks

NBA star and head of the players union, Chris Paul, fired back at Donald Trump on Twitter Saturday after the President took shots at both NBA superstar Stephen Curry and ex-NFL quarterback Colin Kaepernick over the last 24 hours.

Friday night Trump called Kaepernick a "son of a b*tch" during a speech in Alabama, before uninviting Curry from the White House via Twitter Saturday morning, which has set off a war between the unpopular president and some of the biggest stars in sports.

While NFL commissioner Roger Goodell was somewhat diplomatic in his comments, union head Paul went straight for the jugular, challenging the president's manhood.

After first tweeting, "With everything that's going on in our country, why are YOU focused on who's kneeling and visiting the White House??? #StayInYoLane," Paul went for the kill with, "And I doubt he's man enough to call any of those players a son of a bitch to their face..."

Paul was not the only player top land a major hit on Trump, NBA superstar LeBron James chimed in with, " U bum @StephenCurry30 already said he ain't going! So therefore ain't no invite. Going to White House was a great honor until you showed up!"
