Mitt Romney on Supreme Court health care ruling: Romney says he will act to 'repeal Obamacare'

Republican presidential candidate Mitt Romney said Thursday that what the Supreme Court did not do by refusing to strike down President Barack Obama's signature health care law, "I will do on my first day if elected president of the United States."

The Supreme Court upheld the individual insurance requirement at the heart of President Obama's health care overhaul.

The decision means the historic overhaul will continue to go into effect over the next several years, affecting the way that countless Americans receive and pay for their personal medical care. The ruling also handed Obama a campaign-season victory in rejecting arguments that Congress went too far in requiring most Americans to have health insurance or pay a penalty.

Chief Justice John Roberts announced the court's judgment that allows the law to go forward with its aim of covering more than 30 million uninsured Americans.
