Nixon hoped to catch Kennedy cheating on his wife

President ordered spy operations on Kennedy in the early 1970s

The warm and fuzzy bi-partisan tributes to the late “Lion of the Senate,” Ted Kennedy, tend to obscure the fact that he was the bête noire for many Republicans. Certainly Richard Nixon had no love for the man, or his deceased brothers. Oval office tapes from the early 1970s caught Nixon ordering spy operations on Kennedy, hoping to catch him cheating on his then wife, Joan. And the President despairing over her plans to wear hot pants to a White House function.
