The last argument on the Affordable Care Act before the Supreme Court could have consequences far beyond health care.

The key issue is whether the health law's expansion of the Medicaid program for the poor unfairly compels the participation of states. Many considered this to be the weakest part of the states' challenge to the health law, and during Wednesday afternoon's arguments, that seemed to be the case.

The AP says there was strong disagreement between liberal and conservative Supreme Court justices on the question of whether the expansion of Medicaid in the health care law passed in 2010 is constitutional. At issue is whether the federal government can demand that states expand their Medicaid program.

The court's liberal wing, reports the AP, made it clear they were OK with expansion of the program for low-income Americans.

The AP reports:

Amnesty International says the Cuban government has increased its harassment of opposition activists.

According to the human rights organization, the government has detained more 150 opponents and in other situations has surrounded some of the activists' homes to prevent them from "denouncing abuses during Pope Benedict's tour."

Amnesty adds that some human rights organizations and prominent activists have had their phones cut off.

The peace plan backed by the United Nations got the support of Arab foreign ministers today.
