One potential treasury secretary argued for increased control over the Federal Reserve and said that the Dodd-Frank Act has been a "disaster" for the creation of venture capital and small businesses.

"In terms of eliminating the Federal Reserve, that's something I'd like to do in theory, but I don't think it's doable in practice," John Allison said on CNBC's "Closing Bell" on Tuesday. "What I really want to do with the Federal Reserve is control it. You really have an incredibly powerful organization that there's no self-discipline for and it's had a big impact, I believe, on our economic volatility over the years."
