For an all too brief moment last week there was bipartisanship on Capitol Hill as exasperated Democrats and Republicans took turns questioning and berating the CEOs of Fannie Mae and Freddie Mac and their regulator surrounding the issue of executive compensation at the two GSEs.Federal Housing Finance Agency Acting Director Edward DeMarco was called before the Senate Banking, Housing and Urban Affairs Committee and the House Committee on Oversight and Government Reform to explain some $13 million in performance bonuses to Fannie CEO Michael Williams and Freddie CEO Charles Haldeman and eight other senior executives at the taxpayer-subsidized firms.
