Billionaire Mark Cuban is giving President Trump a C-minus on his first 100 days in office.

Asked during an interview on CNN's "New Day" how he would grade Trump's early performance as president, the Dallas Mavericks owner said he would give the real estate mogul a C-minus, arguing that he hasn't implemented any major policy changes since his January inauguration.

"There are some things that he's tried to do," Cuban, an outspoken Trump critic, said in an interview on CNN's "New Day." "I give him credit for the Supreme Court."


"It's a low bar when you do what you say you're going to do," he continued. "No major policy changes at all. Signs a lot of executive orders that he doesn't truly understand. But, you know, there's still hope."

But Cuban also said that, despite Trump's rocky start in office, his supporters see him as fulfilling his promise to shake up Washington by delivering what Cuban calls "political chemotherapy."

"Is he poisonous in a lot of respects? Yeah, this is our chemotherapy," Cuban said. "We hope he's going to change the political system.
