News organizations want a court to force the FBI to admit who the agency paid to hack into a terrorist's iPhone.

FOX's Jared Halpern has more from Washington:

A Freedom of Information Act lawsuit filed in federal court here in D.C. claims to find out who the FBI paid and how much the agency spent to hack into the locked iPhone of one of the San Bernardino shooters.

The Associated Press, Gannett and Vice Media filed the lawsuit after the FBI rejected records requests from the news organizations.

In March, the FBI said it gained access to the locked phone of one of the shooters after getting help from a third-party, but did not reveal any other details.
