An Ohio congressman who spoke out against the civil war?

One notable Ohio congressman who spoke out against the Civil War was Clement L. Vallandigham. A prominent member of the Democratic Party and a leader of the Copperhead movement, Vallandigham opposed the war, arguing that it infringed upon civil liberties and called for a negotiated peace with the Confederacy. His outspoken dissent led to his arrest and banishment to the Confederacy in 1863, highlighting the intense political divisions within the North during the war. Vallandigham's actions and rhetoric exemplified the anti-war sentiment that existed among some northern Democrats.
