The correct response regarding how presidential and congressional reconstruction plans differed is:
The president wanted to bring seceded states back into the Union as quickly as possible.
This reflects the contrasting approaches of President Abraham Lincoln and later President Andrew Johnson, who favored quicker reconciliation and leniency towards the South, versus Congress, particularly the Radical Republicans, who sought a more stringent approach to Reconstruction that aimed to protect the rights of freedmen and impose stricter requirements on Southern states for rejoining the Union.
