Prisoner swap 'violated US law'
The Pentagon violated the law when it swapped five Taliban leaders for Army Sergeant Bowe Bergdahl, who was held prisoner in Afghanistan for five years, US congressional investigators said.
The non-partisan Government Accountability Office said the Defence Department's failure to notify the relevant congressional committees at least 30 days in advance of the exchange broke the law.
The GAO also says the Pentagon's use of funds to conduct the transfer, when no money was available, was a violation of the Antideficiency Act which bars spending by agencies above the amount of money that Congress has authorised.
In May, five senior Taliban were released from Guantanamo Bay, Cuba, in exchange for Sgt Bergdahl, who had disappeared in 2009.
Under exchange terms, the five Taliban are to remain in Qatar for a year.
