John Toussaint Bernard (March 6, 1893[1] – August 6, 1983) was a United States representative from Minnesota.

He went to public schools in both France and in the U.S.[2][3] Bernard worked as an iron-ore miner at the Spruce Mine from 1910 to 1916 or 1917.

[2][3] After leaving the armed forces and returning home, Bernard found himself blacklisted on the Mesabi Iron Range because of earlier efforts to unionize workers.

[2][3] Bernard's single congressional term is notable for his casting the sole vote against an arms embargo against Spain during the Spanish Civil War: Minnesota Congressman John T. Bernard fought throughout his life for working people against strong opposition.

His outspoken and uncompromising views led him, on his second day in office, to cast the single "no" vote in Congress against the Spanish arms embargo.

[7]While in office (1937–1939), Bernard's personal secretary in Washington was Marion Bachrach,[3] sister of John Abt, chief counsel of the Communist Party.

Former Soviet GRU operative Whittaker Chambers named both Bacharach and Abt among others as members of the Ware Group (his first spy network) during his testimony under subpoena to HUAC on August 3, 1948.
