Billionaire and Shark Tank co-host Mark Cuban said Thursday that there is “zero resistance” against antisemitism on X, the social media platform once known as Twitter.

Cuban’s statement follows reposts he made of several antisemitic social media posts, leading some people to believe his account had been hacked. Cuban, who is Jewish, told the Washington Examiner in a statement that his account was not hacked and that he shared the social media posts to showcase “the amount of hate and antisemitism X enables.”
