Trump says Mark Cuban not smart enough to run for presiden

United States President Donald Trump, on Sunday, lashed out at Dallas Mavericks owner, Mark Cuban, saying that the latter is not smart enough to run for president.

Trump took to his twitter handle to state, "I know Mark Cuban well," adding, "He backed me big-time but I wasn't interested in taking all of his calls. He's not smart enough to run for president!"

It came after Cuban, who is a frequent Trump critic, in a veiled attack against the U.S. President, advised the CEOs to be American citizens before speaking out on politics.

He had earlier criticised Trump's travel ban stating that the plan will do more harm than good.

"It wasn't thought out, it was rushed, it was ridiculous. And when something like that happens, it calls into question the management skills of the guy in charge," CNN had earlier quoted Cuban as saying in reference to rollout of the Trump's immigration ban.

Trump's executive order, earlier this year, suspended immigration from seven Muslim-majority countries for 90 days, which have raised terrorism concerns.
