The Obama administration's detention of a high-profile terrorist suspect aboard a Navy vessel is drawing sharp opposition among Republicans in Congress, who say Abu Anas al-Libi should be sent to Guantanamo Bay.

Republican Sens. Lindsey Graham, Kelly Ayotte and Saxby Chambliss say intelligence officials need far more than a couple of months at sea to sufficiently question al-Libi over the 1998 U.S. embassy bombings in Africa and any other al-Qaida terrorist plots. They say a potential civilian trial in New York also is misguided.

Al-Libi, one of the FBI's most wanted terrorists, was captured Saturday in Libya.

Graham accused President Barack Obama of making a political choice not to use Guantanamo, a prison the president has vowed to close.

Democratic Rep. Adam Schiff is among those backing civilian prosecution.
