Identify the president who supported the plan of Radical Reconstruction?

President Andrew Johnson, who succeeded Abraham Lincoln, initially supported a lenient approach to Reconstruction but faced opposition from Radical Republicans in Congress. The Radical Reconstruction plan, which aimed to impose stricter measures on the Southern states and ensure civil rights for freed slaves, was largely driven by Congress rather than Johnson himself. Ultimately, his resistance to the Radical Reconstruction efforts led to his impeachment in 1868.
