The trade group received support from both sides of the political aisle, with Democrats and Republicans criticizing the project. The biggest objection came from New York Republican Congressman Andrew Garbarino, who said the program would “end up hurting consumers.”
After that, Fannie didn’t take long to abandon the program.

This sounds like FHFA's fault for listening, lobbyists gonna lobby
