Which aspect of Abraham Lincoln plan for reconstruction in the south made it differ form the plan of congressional leaders?

Abraham Lincoln's plan for Reconstruction emphasized leniency and forgiveness towards the Southern states, proposing the Ten Percent Plan, which allowed Southern states to rejoin the Union if 10% of their voters took an oath of loyalty. In contrast, congressional leaders, particularly the Radical Republicans, advocated for a more stringent approach that demanded greater protections for the rights of freed slaves and stricter requirements for Southern states to be readmitted, reflecting a desire for a more transformative and punitive reconstruction process. This fundamental difference highlighted Lincoln's aim for reconciliation versus Congress's focus on ensuring civil rights and preventing the resurgence of Confederate power.
