For decades, a graphic letter sent from J. Edgar Hoover's FBI to Dr. Martin Luther King, Jr. was thought to only exist in a censored form. The letter focused on King's sex life and his extramarital affairs. Yale historian Beverly Gage, who's working on a biography of Hoover, recently uncovered an unredacted version of the letter at the National Archives. It begins:

FBI Director James Comey stood flanked by state and local law enforcement while speaking with the media at the bureau’s downtown office yesterday.

It was nearing the end of his workday, and nearing the end of a U.S. field office tour (we’re number 47 of 56 stops) since he took the job just over a year ago.

More than 40 years ago, on the evening of March 8, 1971, a group of burglars carried out an audacious plan. They pried open the door of an FBI office in Pennsylvania and stole files about the bureau's surveillance of anti-war groups and civil rights organizations.

Hundreds of agents tried to identify the culprits, but the crime went unsolved. Until now.

Two and a half weeks ago the FBI, in partnership with local law enforcement, conducted a cross-country sweep looking to help stop child sex trafficking. They recovered dozens of under-age victims who have been forced into prostitution, and they arrested their pimps. Three child victims were found in Washington state, and nine people were arrested here.

On Tuesday,  something very different happened at FBI offices in downtown Seattle.

The FBI is hoping a more detailed timeline and newly released video will revive a stalled investigation into a serial killer suspected of 11 murders -- four of them in Washington state. Israel Keyes committed suicide last year in an Alaska jail cell before agents could identify all his victims.

Over the last several days the FBI, in cooperation with the National Center for Missing and Exploited Children, conducted its seventh cross-country sweep looking to help stop child sex trafficking. The FBI worked with local police agencies, helped recover victims who have been forced into prostitution, and made arrests. About 50 different task forces participated.
