WASHINGTON (Reuters) - U.S. President George W. Bush said on Friday he would sign a $152 billion economic stimulus package into law next week.

The Senate and House of Representatives on Thursday approved the measure, a series of tax rebates and business incentives aimed at staving off an election-year recession in the struggling U.S. economy.

"We are in a period of economic uncertainty and we've acted again," Bush told a conservative conference in Washington. "I want to thank the members (of Congress) for passing a good piece of legislation, which I will sign into law next week."

"This bill reflects our principles. It is robust, it is pro-growth, it stimulates business investment and it puts money into the hands of American consumers," he added.
