WASHINGTON (AP) — Top members of Congress were briefed more than two years ago about the possibility of exchanging an American soldier held captive by the Taliban for five terror suspects at Guantanamo Bay, Cuba, senior Democrats and Republicans said Tuesday.

In a statement, House Speaker John Boehner said lawmakers raised serious concerns that were never satisfactorily answered about the potential swap involving Sgt. Bowe Bergdahl and received assurances from the Obama administration that if a deal were more likely, Congress would be contacted.
