Rep. John Campbell (R-Calif.) waited patiently while Tom Deutsch, the head of the American Securitization Forum, introduced him and bipartisan collaborator Rep. Gary Peters (D-Mich.) at the trade group’s mid-annual meeting in Washington. Campbell and Peters sat quietly, occasionally smiling at the crowd of 50 or so attendees. The two congressmen were set to make a case for newly filed legislation to ultimately replace Fannie Mae and Freddie Mac with a new mortgage finance system.
