Lamphere was responsible for a 1949 sting operation that led to the arrest and trial of Justice Department employeee Judith Coplon.Tim Weiner, Enemies: A History of the FBI, Allen Lane, 2012, p.163.
In around 1949, Lamphere deduced that a paper on uranium exposive in the Venona decrpyts had been written by Klaus Fuchs.Chapman Pincher, Treachery: Betrayals, Blunders and Cover-Ups: Six Decades of espionage, Mainstream Publishing, 2012, p.2295.
Between February and May 1950, Lamphere was forbidden by J. Edgar Hoover to give any information on counterintelligence investigations to MI5.Chapman Pincher, Treachery: Betrayals, Blunders and Cover-Ups: Six Decades of espionage, Mainstream Publishing, 2012, p.611.

In April 1951, Lamphere attended a party at the Washington home of Kim Philby.
