Looks like it although is says he went after Gotti:
John Gleeson
He (Gleeson) was an Assistant United States Attorney for the Eastern District of New York from 1985 to 1994 where he was noted for his prosecution of Mafia cases, most notably that of Gambino crime boss John Gotti which resulted in Gotti's conviction.
And you may recall, John Durham provided evidence to put Gotti behind bars:
By the early '90s, working out of the U.S. attorney's office in Connecticut, he (Durham) was receiving national attention heading cases against New England crime kings, providing evidence to put John Gotti behind bars, and going after crooked politicos like former Connecticut governor John Rowland.
