Washington, D.C. ? Little-known documents made public Thursday detail illegal and scandalous activities by the CIA more than 30 years ago: wiretappings of journalists, kidnappings, warrantless searches and more.

The documents provide a glimpse of nearly 700 pages of materials that the agency has declassified and plans to release next week.

A six-page summary memo declassified in 2000 and released by The National Security Archive at George Washington University outlines 18 activities by the CIA that “presented legal questions” and were discussed with President Ford in 1975.

CIA Director Michael Hayden called the documents being released next week unflattering, but he added that “it is CIA’s history.”

“The documents provide a glimpse of a very different time and a very different agency,” Hayden told a conference of historians on Thursday.
