After Lincoln’s death, why was there tension between Republicans and Congress and President Andrew Johnson regarding reconstruction? Select two

Under John’s plan, the south would remain as a conquer nation
Johnson’s plan allowed former confederate officers to be elected to high offices
Johnson planned to guarantee the political and civil rights of freedmen
Johnson’s plan allowed the new southern governments to pass black codes that restricted African-Americans freedom

1. Johnson's plan allowed former Confederate officers to be elected to high offices, which angered Republicans in Congress who believed that former Confederates should be punished and excluded from holding positions of power.

2. Johnson's plan allowed the new southern governments to pass black codes that restricted African-Americans' freedom, which went against the Republican desire to ensure the political and civil rights of freedmen. This tension further escalated as Republicans in Congress believed that Johnson was not properly enforcing these rights and protections for African-Americans in the South.
