In November 1953, Attorney General Herbert Brownell would allege in a speech that Truman had nominated a Soviet spy—senior Treasury Department official Harry Dexter White—to serve as the U.S. Executive Director of the International Monetary Fund, despite what Brownell said was the President's awareness of White's involvement in Soviet espionage. And on December 3, 1953, President Eisenhower directed that a "blank wall be placed between Dr. J. Robert Oppenheimer and secret data"—marking the beginning of the process that led to the Atomic Energy Commission's suspension of Oppenheimer's security clearance later in December and its 4-to-1 decision on June 28, 1954, against restoring the clearance.
