Why was Andrew Johnson and congress feuding?

Andrew Johnson and Congress were feuding primarily over Reconstruction policies following the Civil War. Johnson, a Southern Democrat, favored lenient terms for the South and sought to quickly restore their political power, which clashed with the more radical Republican majority in Congress that wanted to enforce civil rights and ensure the protection of Freedmen. This conflict culminated in Johnson’s vetoes of key legislation and led to his impeachment in 1868, as Congress sought to limit his power and push for a more stringent approach to Reconstruction.
