In 1941, Charles Lindbergh, who achieved fame by being the first person to fly solo across the Atlantic Ocean, delivered an anti-Semitic speech on the radio. Lindbergh became an outspoken supporter of Nazi Germany, even recommending in testimony before Congress that the U.S. negotiate a neutrality pact with Germany. At a rally in Des Moines, Iowa, he made an infamous speech claiming that Jews, "for reasons which are not American, wish to involve us in the war... We cannot allow the natural passions and prejudices of other people to lead our country to destruction." Lindbergh also made an implicit threat against Jews, stating: "Instead of agitating for war, the Jewish groups in this country should be opposing it in every possible way, for they will be among the first to feel its consequences."
