Andrew Johnson Trial

Throughout the two-month-long trial, Johnson's defense lawyers repeatedly saw their sound legal arguments thwarted by purely political forces. However, seven Republican senators were disturbed by how the proceedings had been manipulated in order to give a one-sided presentation of the evidence. Senators William Pitt Fessenden, Joseph S. Fowler, James W. Grimes, John B. Henderson, Edmund G. Ross, Lyman Trumbull, and Peter G. Van Winkle defied their party and public opinion and voted against impeachment.

The Senate met on 26 May 1868, for the final vote. The shift by the seven Republicans proved critical: the tally was 35-19 in favor of impeachment, one vote short of the two-thirds majority necessary to impeach Johnson. Johnson was acquitted. But his political career never recovered. Later in 1868 the war hero General Ulysses S. Grant was elected the next president of the United States.
