The Department of Defense was putting together a plan to include Caitlan Coleman of York , Pa., her baby who was born in captivity and her Canadian husband, Joshua Boyle, in any deal to free Bergdahl, said Joe Kasper, chief of staff to Rep. Duncan Hunter, R-Calif., who sits on the House Armed Services Committee.

Among Americans held captive is Warren Weinstein, a contractor from Rockville, Md., who was abducted in 2011 in Pakistan, is being detained by al-Qaeda militants aligned with the Taliban.

“The DoD was looking at this in the whole of scope of things, to deal with these people as well,” Kasper said. “Instead of five for one, why not five for five?”

In a June 2 letter to President Obama, Hunter said the Defense Department plan, which Hunter said did not have time to materialize before negotiations headed by the State Department gained Bergdahl’s release, did not include a prisoner exchange.
