Mark Cuban expressed doubts that President Donald Trump would serve out his entire term.
The billionaire investor and reality TV star gave the president, whom he criticized often during the campaign, mixed reviews after three weeks on the job, reported TMZ.
"Some of his policies are fine, right, some of his Republican-driven policies -- tax reform, reduction of bureaucracy," Cuban said. "There are a lot of positives there, but I don't think those are necessarily his ideas, and the execution, particularly on the ban, has been horrible -- I mean, I don't think he lasts four years."
Cuban didn't elaborate, and he declined to comment on his meeting last month with Trump's chief strategist, Steve Bannon.
"Look, it's our country, we want him to do well and want the country to do well, there's a lot of great opportunity here," Cuban said. "It's not about policies -- it's about temperament, it's about approach, it's about investing the time to learn."
Cuban, a heavy social media user himself, said he appreciated Trump's tweets as a window into his thoughts, but he doesn't understand his attacks against the press.
"Facebook doesn't have a character limit," he said. "Instead of having Sean Spicer go out there and just try to respond to everything, pre-empt the whole thing by going in-depth about all your policies and tell us what you're thinking. The challenge is, I don't know that he knows what he's thinking."
