Federal Reserve governor Daniel Tarullo was central to the implementation of the Dodd-Frank Act, which imposed tougher regulations on banks in the wake of the financial crisis. Though his term isn't up until 2022, Tarullo is now stepping down, just as President Trump is expected to scale back much of the regulation put in place. Tarullo joins economics correspondent Paul Solman for a conversation.
