Sen. Tammy Baldwin (D-WI) and Rep. Elijah Cummings (D-MD) recently introduced the Financial Services Conflict of Interest Act, which takes aim at the "revolving door." This term refers to people who move from the private sector, to public agencies or Capitol Hill offices, and back to private companies, often bringing undue corporate influence along for the ride. Sens. Elizabeth Warren (D-MA) and Brian Schatz (D-HI) cosponsored the legislation.
