8. The passage of the bill over the veto placed Johnson in a situation in which a collision was almost sure to come. As the chief executive of the country he was charged with the duty of carrying out the provisions of the reconstruction acts, notwithstanding his strong personal repugnance to them. Under the advice of Attorney-General Stanbery he had construed the acts literally, and he had thus frustrated in part the object of the legislation. But the co-operation of the army was necessary, and unfortunately for President Johnson, the Secretary of War, Mr. Stanton, strongly opposed his views, and conducted himself as far as possible in accordance with the wishes of the congressional majority. The continued friction between the President and the Secretary of War seemed to President Johnson to necessitate Stanton's retirement, but repeated hints to that effect were not recognized by the latter. Finally, on August 5, 1867, the President informed him that "public considerations of a high character constrained" him to say that his resignation would be accepted. The Secretary's prompt reply was that "public considerations of a high character" constrained him not to resign until the next session of Congress. A week later, August 12, the President formally suspended him and appointed General Grant Secretary _ad interim_.[188] Stanton then submitted "under protest to superior force." When Congress met in December the President reported his suspension of Stanton, and after long discussion the Senate, on January 13, 1868, refused to concur.[189] When informed of this action of the Senate, General Grant immediately turned over the Secretary's office to Stanton, thus definitely committing himself to the congressional interpretation of the law. Grant's action was a sore disappointment to the President. Johnson had refused to accept the Tenure-of-Office Act as constitutional, and had purposed to make this a test case. In the correspondence which passed between him and General Grant after the latter's acquiescence in the action of the Senate, Johnson claimed that it was understood that Grant was either to refuse to give up the office to Stanton, or, if he should be unwilling to take so prominent a part in the contest, to resign and permit the office to be filled with some one whose views agreed with the President's, so that Stanton, if he sought to regain the office, might be compelled to resort to the courts. In this way the constitutionality of the act could be tested. Johnson's statements as to the understanding with Grant were substantially endorsed by the Cabinet, on the strength of a conversation between Johnson and Grant at a cabinet meeting. Grant, however, firmly denied that there was any such agreement or understanding.[190]
