WASHINGTON - President Barack Obama scored two major endorsements for his health overhaul push Thursday and trumpeted the news as House Democratic leaders pushed toward a vote Saturday on far-reaching legislation remaking the U.S. health care system.

"I am extraordinarily pleased and grateful to learn that the AARP and the American Medical Association are both supporting the health insurance reform bill that will soon come up to vote in the House of Representatives," Obama said in an unannounced visit to the White House briefing room.
