Watch: Bill O'Reilly spars with Mark Cuban over Trump's 'lack of leadership' and 'inconsistency

Billionaire Mark Cuban, one of President Donald Trump's most outspoken critics, said on Fox News Tuesday that his biggest concerns with the Trump administration so far are the president's management style and leadership skills.

Speaking with Fox News host Bill O'Reilly, Cuban explained that he has no confidence in Trump's ability to lead, given the tumultuous first weeks Trump has had in the White House.

"I don't think he's been able to show any leadership, I don't think he's taken responsibility for the White House, and I don't think he's shown [his White House staff] any direction," Cuban said.

Explaining why he believes Trump lacks leadership skills, Cuban cited the "divergence in communication" and the "fearful" attitude of many White House staffers — including senior staff — which Cuban said is likely the reason behind the massive number of leaks coming from Trump's White House.

"The inconsistency coming out of the White House is a huge problem," Cuban said.

O'Reilly, however, wanted to have a discussion about where Cuban disagrees with Trump on policy issues, and the billionaire investor was more than happy to oblige the Fox host.

Cuban acknowledged that Trump has been very active in his first weeks as president but said that Trump doesn't yet understand that the "nature of work is changing" and that simply nickle-and-diming jobs here and there won't lead to a long-term, sustained job market.

"He's shuffling deck chairs on the Titanic by going and talking to these companies and dealing with five and 10 and even 25,000 jobs at time," Cuban said, adding that there's "nothing wrong" with working with companies to hire more Americans, but he stressed that Trump must start dealing with the "macro" issues.

After some back and forth with O'Reilly, Cuban ceded that he will give Trump one year in office to see if his aggressive approach works but again expressed his concern that he doesn't believe Trump "understands the bigger picture."

Explaining that the next three years will see more technological changes than the previous 30 years, Cuban said the challenge of the administration will be to find places in the job market to create innovation as artificial intelligence and neural networks take over in others.
