WASHINGTON (AP) — Republican Sen. Kelly Ayotte asked the Pentagon on Wednesday to take every reasonable step to make sure that the five Taliban leaders released from the U.S. prison at Guantanamo Bay, Cuba, in exchange for Sgt. Bowe Bergdahl are not allowed to return to the battlefield in Afghanistan. Ayotte, R-N.H., also reiterated her opposition to the swap, which the Obama administration conducted without notifying Congress. On the flip side, Afghanistan's peace council in 2011 requested the release of one of the five, Khairullah Khairkhwa, from Guantanamo because it thought he might be able to help foster reconciliation talks with the Taliban.
