Watergate's [inside] man!

[Scott Kaiser]

Watergate had an [inside] man, and many believed this man was the sixth burglar. He stayed at the Watergate hotel. He helped in providing and removing tape placed on door locks whenever there was a plot to break-in. In-fact, after three successful break-ins it was the fourth break-in at 2:00 AM when the tape was removed by someone else other then the [inside] man, Frank believed it was the [inside] man who had removed the tape. It was this act that ultimately disclosed the entire operation said Frank.

Could anyone help me out with who the [inside] man was?
