According to recently uncovered KGB documents the disingenuous Senator from Massachusetts attempted to conspire with the Soviet Union to undermine the reelection campaign of President Ronald Regan.

In his book, which came out this week, Kengor focuses on a KGB letter written at the height of the Cold War that shows that Sen. Edward Kennedy (D-Mass.) offered to assist Soviet leaders in formulating a public relations strategy to counter President Reagan’s foreign policy and to complicate his re-election efforts.

The letter, dated May 14, 1983, was sent from the head of the KGB to Yuri Andropov, who was then General Secretary of the Soviet Union’s Communist Party.

In his letter, KGB head Viktor Chebrikov offered Andropov his interpretation of Kennedy’s offer. Former U.S. Sen. John Tunney (D-Calif.) had traveled to Moscow on behalf of Kennedy to seek out a partnership with Andropov and other Soviet officials, Kengor claims in his book.
