Supreme Court to hear Obama health care challenge

The Supreme Court has said it will hear a case challenging the constitutionality of President Obama's health care overhaul. Oral arguments will likely take place in March, and a ruling is expected in June. Several lawsuits argue that the law's requirement that almost all Americans must buy health insurance violates the constitution's Commerce Clause. Some courts have rejected that claim, but others have upheld it, making it all but certain that the Supreme Court would step in to resolve the issue.
