The CIA says its inspector general has found nothing wrong with the spy agency's close partnership with the New York Police Department.
The inspector general concluded that no laws were broken and there was no evidence the CIA was conducting domestic spying.
The inspector general decided to do a preliminary investigation after a series of stories by The Associated Press revealed how after the 9/11 attacks the CIA helped the NYPD build domestic intelligence programs that were used to spy on Muslims.
The revelations troubled some members of Congress and even prompted the U.S. director of national intelligence, James Clapper, to remark that it did not look good for the CIA to be involved in any city police department.
The NYPD continues to have a close relationship with the CIA.
