World War II

O'Hara was an outspoken ally of Charles Lindbergh, and was an avowed isolationist. This was considered particularly egregious at the time because this was after the fall of France and before Hitler's invasion of the Soviet Union, and at that time Britain was very much alone. After an especially contentious argument outside of congress over a bill titled H.R. 1776 (which provided funding for the British military in early 1941), Edward E. Cox, Stephen Pace, Paul Brown, Albert Sidney Camp, Carl Vinson, Sam Hobbs, Pete Jarman, Henry B. Steagall, George M. Grant, Frank W. Boykin, L. Mendel Rivers, James P. Richards, Hampton P. Fulmer, Herbert Covington Bonner and John L. McMillan all denounced O'Hara to the press. All 15 of the aforementioned southern representatives attacked O'Hara personally when speaking to the media. Richards said that O'Hara's "lack of manhood was only surpassed by his lack of sense." George M. Grant called O'Hara "two-faced and gutless." Hery B Steagall said it was "unfortunate that Mr. O'Hara has no sense of honor." Herbert Covington Bonner called him "unmanly and shameful." Hampton P. Fulmer said O'Hara was "nothing but a damned fool." Peter Jarman said that "When Hitler says jump, Mr. O'Hara asks How High?." When asked "Do you respect Representative O'Hara?", Albert Sidney Camp responded "No!" Edward E. Cox said that it was "a shame, because Joseph O'Hara was a man once."^[1]

O'Hara voted against the Civil Rights Act of 1957.^[2]
