Anthony "Tony" Ulasewicz (December 14, 1918 in New York, United States – December 17, 1997 in Glens Falls, New York) was a figure in the Watergate scandal, delivering hundreds of thousands of dollars in "hush money" to Watergate defendants G. Gordon Liddy and E. Howard Hunt. He also investigated the lives of notable Democrats like Senator Edward M. Kennedy. He was of Polish descent.
Tony knew a lot about the Kennedies.
Even though the context tells us Tony investigated the Kennedies, we do not know the extent of the information Tony gathered about them.
