Stanton, although of a domineering and brusque personality, had ably administered the War Department under Lincoln and Johnson. During the controversy between the President and Congress, Stanton had remained in the Cabinet but was closely in touch with his chief's opponents and had even drafted one of the reconstruction acts. Johnson had tolerated the questionable conduct of his Secretary, despite the advice of many of his supporters, until August 5, 1867, when he requested Stanton's resignation. The latter took refuge behind the Tenure of Office Act, denying the right of the President to remove him, but yielding his office at Johnson's insistence. This episode had occurred during a recess of Congress and, in accord with the law, the removal of Stanton was reported when it convened in December. The Senate at once refused to concur and Stanton returned to his office. The President now found himself forced, by what he regarded as an unconstitutional law, into the unbearable position of including one of his enemies within his official family, and once more he ordered the Secretary to retire. But meanwhile the House of Representatives had been active and had on February 24, 1868, impeached the President for "high crimes and misdemeanors." The trial was conducted before the Senate, as the Constitution provides, the Chief Justice of the Supreme Court acting as the presiding officer. The House chose a board of seven managers to conduct the prosecution, of whom Thaddeus Stevens and Benjamin F. Butler were best known. The President was defended by able counsel, including former Attorney-General Stanbery, Benjamin R. Curtis, who had earlier sat upon the Supreme Court, and William M. Evarts, an eminent lawyer and leader of the bar in New York. The charges, although eleven in number, centered about four accusations: (1) that the dismissal of Secretary Stanton was contrary to the Tenure of Office Act; (2) that the President had declared that part of a certain act of Congress was unconstitutional; (3) that he had attempted to bring Congress into disgrace in his speeches; and (4) that in general he had opposed the execution of several acts of Congress. The President's counsel asked for forty days in which to prepare their case. They were given ten, although members of the House had been preparing for more than a year to resort to impeachment. The trial lasted from early March to late May.
