Virginia Attorney General Ken Cuccinelli plans to weigh in with his views on the U.S. Supreme Court's ruling upholding the key provision of President Barack Obama's health care overhaul.

In a statement, the Attorney General says "this is a dark day for the American people, the Constitution, and the rule of law."

The ruling was issued Thursday morning, and Cuccinelli has announced plans for a news conference after he examines the decision.

Cuccinelli attended the Supreme Court's arguments in the case in March. He believes the law's requirement that individuals buy health insurance or pay a penalty is unconstitutional. That's a view shared by the 26 states involved in the Supreme Court case.

Cuccinelli filed a separate lawsuit against the law, but a federal judge's ruling in his favor was overturned when a federal appeals court ruled that Virginia lacked legal standing to challenge the law.
