Exclusive: FBI may have destroyed files on Walter Cronkite

FBI spokesman: 'We would need warehouses to keep everything we've collected'

WASHINGTON -- Officials with the Federal Bureau of Investigation said they may have destroyed files on legendary newsman Walter Cronkite in an October 2007 document purge.

Blogger and San Francisco-based gay activist Michael Petrelis filed a Freedom of Information Act request after the CBS anchorman's death in mid-July for access to FBI documents containing Walter Cronkite's name. The FBI restricts third-party access to information about individuals while they are still alive, but makes it possible for people to request copies of someone else's FBI files after they have passed away.
