This was the high point of Crouch's career. He testified in major trials in Maryland, Hawaii, and Washington State and helped convict dozens of Communists. He also warned President Dwight D. Eisenhower and the nation at large of the Communist threats emanating from Hawaii and Latin America. He thus opposed making Hawaii a state and demanded the nation do more to appreciate the Communist threat to its immediate south. His most surprising testimony of this period was his accusation of Charlie Chaplin as a Communist. Though Crouch was the only person to make that claim publicly, it had enough weight to force Chaplin from the country. Such success, however, was mitigated by the first public attacks on his veracity. Joseph and Stewart Alsop began to question Crouch's testimony and for the first time raised questions about him in the press. Crouch survived this initial inquest, however, and continued to enjoy the fruits of his anti-Communist activism.
