FILE - FBI Director James B. Comey speaks during a news conference in Portland, Ore., in this Oct. 1, 2014 file photo. In a letter ThursdayNov. 6, 2014 to The New York Times, Comey said the agent "portrayed himself as an employee of The Associated Press" to help catch a 15-year-old suspect accused of making bomb threats at a high school near Olympia, Washington. It was publicized last week that the FBI forged an AP story during its investigation, but Comey's letter revealed the agency went further and had an agent actually pretend to be a reporter for the wire service.

WASHINGTON — The Associated Press is demanding assurances that the FBI will never again impersonate a member of the news media.

The demand was made in a letter Monday from Gary Pruitt, the AP president and CEO, to FBI Director James Comey and Attorney General Eric Holder.

The letter comes days after Comey revealed that an FBI agent in Seattle in 2007 had portrayed himself as an AP journalist during an investigation into a teenager suspected of making bomb threats at a high school.

Comey said the technique was legal but likely would have required additional layers of approval today.

In the letter, Pruitt demanded to know who authorized the impersonation, the process that was followed for its approval and whether such operations are still being carried out.
