In a series of tweets on Friday, billionaire entrepreneur Mark Cuban challenged Donald Trump to an interview, offering to give $10 million to the charity of Trump’s choice if he could grill the Republican nominee on his policies for four hours.
Cuban has frequently taken to social media—and late-night talk shows—to taunt or criticize Trump throughout the presidential campaign. Cuban also said he would have considered being Hillary Clinton’s running mate.
Trump, who has faced scrutiny over following through on charitable donations, has not yet responded to the challenge. Cuban proposed a one-on-one detailed interview that makes no mention of Clinton.
“I’ll add an option. If you need it, I’ll write you the check and you can keep the money rather than give it to charity,” Cuban wrote on Twitter.
