"Rep. Andy Barr, the chair of the House financial institutions subcommittee, discusses why he should lead Republicans on the Financial Services Committee next year. He offers a preview of his agenda, including pushing legislation that would prevent banks from denying legal businesses access to financial services and why large institutions are suddenly supporting it. He also details what changes regulators should make in new Basel III capital rules, how regulatory reform for banks could happen, and why M&A approval rules should be revamped."
