(Tuesday, October 10, 1972, during the Watergate scandal) — FBI agents have established that the Watergate bugging incident stemmed from a massive campaign of political spying and sabotage conducted on behalf of President Nixon’s re-election and directed by officials of the White House and the Committee for the Re-election of the President, the Washington Post reported today.

The activities, according to information in FBI and Department of Justice files, were aimed at all the major Democratic presidential contenders and — since 1971 — represented a basic strategy of the Nixon re-election effort.

During their Watergate investigation, federal agents established that hundreds of thousands of dollars in Nixon campaign contributions had been set aside to pay for an extensive undercover campaign aimed at discrediting individual Democratic presidential candidates and disrupting their campaigns.

“Intelligence work” is normal during a campaign and is said to be carried out by both political parties. But federal investigators said what they uncovered being done by the Nixon forces is unprecedented in scope and intensity.

They said it included:

Following members of Democratic candidates’ families and assembling dossiers on their personal lives; forging letters and distributing them under the candidates’ letterheads; leaking false and manufactured items to the press; throwing campaign schedules into disarray; seizing confidential campaign files; and investigating the lives of dozens of Democratic campaign workers.
