A watchdog group on Thursday filed suit against the CIA for information on the role that political appointees have played in obstructing the agency’s response to requests made under open record laws.

The suit, filed by nonprofit Cause of Action, comes after the CIA refused to release records responsive to a congressional investigation into obstruction by 29 federal agencies. Though the records at the center of the suit were created by the CIA Inspector General, it’s up to the CIA to decide whether to release them.
