From the New York Times of 27 June 2007, about a just released batch of CIA documents.
"One technician was arrested in 1960 after trying to bug a Las Vegas hotel room. The operation had been requested by Sam Giancana, the Chicago mobster, who was then helping the C.I.A. in a plot to assassinate Mr. Castro. Mr. Giancana had been concerned that his girlfriend, the singer Phyllis McGuire, was having an affair with the comedian Dan Rowan, and surveillance was ordered to "determine the extent of his intimacy" with her."
I think this is a 'telling' incident on several fronts.
