Sen. Heidi Heitkamp believes the financial industry "isn't just about numbers," and is concerned that the regulations coming out of the 2010 Dodd-Frank Act do not "take into consideration long-term relationship banking."

The North Dakota Democrat argues that the reform law should be fully implemented before additional rules are enacted.

"You passed a whole big bill that has yet to be completely implemented and you don't know what the consequences are going to be of complete implementation," she said. "Until you get there, I don't know that passing mandates in terms of breakups is the way to go."
