U.S. seizes Fannie and Freddie

NEW YORK (CNNMoney.com) -- Federal officials on Sunday unveiled an extraordinary takeover of Fannie Mae and Freddie Mac, putting the government in charge of the twin mortgage giants and the $5 trillion in home loans they back.

The move marks Washington's most dramatic attempt yet to shore up the nation's housing market, which is suffering from record foreclosures and falling prices.

The sweeping plan, announced by Treasury Secretary Henry Paulson and James Lockhart, director of the Federal Housing Finance Agency, places the two companies into a "conservatorship" to be overseen by the Federal Housing Finance Agency. Under conservatorship, the government would temporarily run Fannie and Freddie until they are on stronger footing.
