Supporters are defending a House Republican proposal to liquidate Fannie Mae and Freddie Mac and let the private market fill in the gaps. But despite a nearly complete lack of bipartisan support and even doubts from within his own party, the author of the proposal is pushing hard to fast-track the bill. This week, the House Financial Services Committee heard testimony from 11 experts on the Protecting American Taxpayers and Homeowners Act, introduced last week by Rep. Jeb Hensarling, R-TX.The PATH Act is a comprehensive proposal to create a sustainable housing finance system by ending the federal governments domination of the housing finance market and give consumers more choices in determining which mortgage product best suits their needs, said Hensarling.
