In June 1939, Moseley testified for five hours before the House Un-American Activities Committee. He said that a Jewish Communist conspiracy was about to seize control of the U.S. government. He believed the President had the authority to counteract the planned coup and could do so "in five minutes" by issuing an order "to discharge every Communist in the government and everyone giving aid and comfort to the Communists." He said the President could use the army against "the enemy within our gates" but did not seem willing to do so. He said he held no anti-Semitic views and that "the Jew is an internationalist first ... and a patriot second." He praised the "impressively patriotic" German-American Bund and said its purpose was to "see that Communists don't take over the country." Among Moseley's supporters who attended the hearing were Donald Shea, head of the American Gentile League and James True of America First Inc. The Committee found a prepared statement he read into the record so objectionable it was deleted from the public record. A few days later, Thomas E. Stone, head of the Council of United States Veterans, accused Moseley of treason and wrote that his praise of the Bund "abets a foreign government in the preparation of disruption against the eventuality of possible future hostilities, and that this he is acting in treason to our national safety."
