Washington (CNN) -- President Obama signed sweeping health care reform legislation into law Tuesday, hailing the moment as the latest example of America facing up to major challenges for the benefit of all its people. The bill constitutes the biggest expansion of federal health care guarantees in more than four decades, and its enactment was a giant victory for Obama and Democrats after a brutal legislative battle dating back to the start of his presidency. No Republicans supported the bill in either the House or Senate, and Democratic leaders needed a separate bill that calls for changes in the new law in order to get enough support in the House to pass the measure.
