Comey had been leading the bureau’s investigation into Russia’s meddling in the United States election and any potential ties between Trump’s campaign staff members and Russia. 

“I think, without question, we got a guy that’s on the right agenda with crappy management practices,” Welch, who the network noted has Trump's ear, added.

Welch told the business network that he gives Trump a “D” grade for his management style, but an “A” for his approach to policy.

Welch last September announced that he would vote for Trump, citing the then-GOP nominee’s plan to slash the corporate tax rate and roll back government regulations.
