The Arizona senator blasted the ruling at a town hall forum in Pemberton, N.J. today, saying it will "hurt our ability" to protect the U.S. from terrorists.
A proponent of closing the Guantanamo prison, McCain reacted more mildly to the ruling when asked about it yesterday.
"These are unlawful combatants, they are not American citizens and I think we should pay attention to Justice Roberts' [dissenting] opinion in this decision," McCain said yesterday. "But it is a decision that the Supreme Court has made. Now we need to move forward. As you know I always favored closing Guantanamo Bay and I still think we ought to do that."
