WASHINGTON – President Bush on Wednesday signed a massive housing bill intended to provide mortgage relief for 400,000 struggling homeowners and stabilize financial markets.

Bush signed the bill without any fanfare or signing ceremony, affixing his signature to the measure he once threatened to veto, in the Oval Office in the early morning hours. He was surrounded by top administration officials, including Treasury

Secretary Henry Paulson and Housing Secretary Steve Preston.

“We look forward to put in place new authorities to improve confidence and stability in markets,” White House spokesman Tony Fratto said. He said that the Federal Housing Administration would begin right away to implement new policies “intended to keep more deserving American families in their homes.”
