WASHINGTON (AP) — Opponents of the Affordable Care Act say they won't let go. They're taking their latest challenge of President Barack Obama's health care overhaul to the Supreme Court, filing a new appeal today.

The Pacific Legal Foundation contends the law violates the provision of the Constitution that requires tax-raising bills to originate in the House of Representatives.

They say if they lose this one, they'll keep filing other appeals.

The court has already turned back two major challenges.
