WASHINGTON (AP) — The fate of President Barack Obama's health care overhaul was cast into peril Tuesday as the Supreme Court's conservative justices sharply and repeatedly questioned its core requirement that virtually every American carry insurance. The court will now take up whether any remnant of the historic law can survive if that linchpin fails.

The justices' questions in Tuesday's hearing carried deeply serious implications but were sometimes flavored with fanciful suggestions. If the government can force people to buy health insurance, justices wanted to know, can it require people to by burial insurance? Cellphones? Broccoli?

The law, pushed to passage by Obama and congressional Democrats two years ago, would affect nearly all Americans and extend insurance coverage to 30 million people who now lack it. Republicans are strongly opposed, including the presidential contenders now campaigning for the chance to challenge Obama in November.
