The FBI is resisting a request to turn over thousands of classified phone intercepts to a Margate man suing the U.S. government for malicious prosecution before the Justice Department dropped charges that he supported a Pakistani Taliban terror group.

The FBI contends in court documents it would take about two years to declassify and translate up to 40,000 calls—most are in the Pashto and Urdu languages—before they could be provided to Irfan Khan’s attorney, Michael Hanna.
