For years, mortgage giants Fannie Mae and Freddie Mac tenaciously worked to nurture, and then protect, their financial empires by invoking the political sacred cow of homeownership and fielding an army of lobbyists, power brokers and political contributors. Now, new attention is being focused on the bruised mortgage companies as the Bush administration presses its rescue plan to Congress. (AP Photo/Pablo Martinez Monsivais, File)
