Marking a pivotal point in the presidential campaign, the Supreme Court's decisionto uphold President Barack Obama's sweeping federal health care law handed the Democratic incumbent crucial election-year vindication for his signature legislative accomplishment.
Republican rival Mitt Romney, an ardent opponent of the law, prepared to use the decision for his own political gain and planned to cast himself as the next best hope for the millions of Americans who favor the law's repeal.
The decision put an end to what had been one of the biggest unknowns in the presidential race. Four months from Election Day, both Obama and Romney will seek to use the high court ruling to bolster their vision for the country, as well as raise money for their campaigns.
Both were expected to comment on the decision later Thursday from Washington, with Obama scheduled to speak at the White House around midday.
