Bob Johnson, the founder of Viacom's BET Network, has spoken out in praise of President Donald Trump.

During a recent interview with CNBC, Johnson criticized the Democrats for moving "too far left" and thinks that the economy is flourishing under Trump's leadership.

"The party in my opinion, for me personally, has moved too far to the left," Johnson told CNBC's Hadley Gamble.

"And for that reason, I don't have a particular candidate (I'm supporting) in the party at this time," he said. "I think at the end of the day, if a Democrat is going to beat Trump, then that person, he or she, will have to move to the center and you can't wait too long to do that."

Despite Trump's trade war with China - which could eventually cripple the US market, he thinks that Trump is doing well:

"I think the economy is doing great, and it's reaching populations that heretofore had very bad problems in terms of jobs and employments and the opportunities that come with employment … so African-American unemployment is at its lowest level," Johnson said.

"I give the president a lot of credit for moving the economy in a positive direction that's benefiting a large amount of Americans," he said. "I think the tax cuts clearly helped stimulate the economy. I think business people have more confidence in the way the economy is going."

Adding that "overall, if you look at the U.S. economy … you got to give the president an A+ for that."

Under Trump's leadership, corporations are now paying the lowest taxes they've shelled out in years, while the lower and middles classes are forking out some of the highest.
