Legislation introduced this week by a bipartisan group of senators would seek to “jumpstart” the stalled effort in Congress to implement legislative reform of Fannie Mae and Freddie Mac, but industry observers say the measure may also act to hinder cash grabs by government officials when the Treasury Department begins its “sweep” of the GSEs’ profits. The Jumpstart GSE Reform Act – sponsored by Sen. Bob Corker, R-TN, with co-sponsors Sens. Mark Warner, D-VA, David Vitter, R-LA, and Elizabeth Warren, D-MA – would prohibit any increase in Fannie’s and Freddie’s guaranty fee from offsetting other government spending. “The reality is that if Congress were to spend g-fee revenue from the GSEs on other programs, reforming these mortgage behemoths would become nearly impossible,” said Corker.
