"In 2003, while the ranking Democrat on the Financial Services Committee, Frank opposed a Bush administration proposal for transferring oversight of Fannie Mae and Freddie Mac from Congress and the Department of Housing and Urban Development to a new agency that would be created within the Treasury Department. The proposal reflected the administration's belief that Congress "neither has the tools, nor the stature" for adequate oversight.
