What did president Johnson do to prevent being impeached?

President Andrew Johnson sought to avoid impeachment by actively defending his policies and decisions, particularly regarding Reconstruction and his use of presidential power. He attempted to rally public support and appealed to moderate Republicans in Congress, arguing that his actions were in line with the Constitution. Johnson also engaged in political maneuvering, such as appointing officials who supported his agenda and attempting to undermine his opponents. Ultimately, his efforts delayed impeachment but did not prevent it, as he was impeached in 1868, primarily over his violation of the Tenure of Office Act.
