What was the problem with confederates being apart of congress?

The problem with Confederates being part of Congress stemmed from their prior allegiance to the Confederacy during the Civil War, which raised questions about their loyalty to the United States. Their inclusion could undermine the federal government's authority and complicate efforts for Reconstruction. Many in Congress believed that allowing former Confederates to hold office would hinder progress toward reconciliation and the integration of formerly enslaved individuals into society. This led to significant debates about eligibility and representation in the post-war government.
