But anti-Communist sentiments in the U.S. would again interfere with his plans. In late December 1952 a well-known but unreliable

his old nemesis Ruth Shipley again recommended denial. He received his passport only after swearing in writing and in her

Congressional committees are not interested in learning and disclosing the truth."
