Why did the Republicans in Congress feel that the 14th amendment was necessary

They were the wealthy, southern planters would not comply with the civil rights act
They worried that President Johnson would not enforce the civil rights act
They worried that the south would secede from the union again
They worried that the Supreme Court would find the civil rights act unconstitutional

The Republicans in Congress felt that the 14th amendment was necessary because they were concerned that the southern states, particularly the wealthy southern planters, would not comply with the Civil Rights Act and would continue to oppress and discriminate against newly freed slaves. They also feared that President Johnson, who was often lenient towards the former Confederates, would not enforce the Civil Rights Act. Additionally, there were concerns that the southern states might again try to secede from the Union, leading to another civil war. Lastly, there was a fear that the Supreme Court might find the Civil Rights Act unconstitutional, so they wanted to enshrine the rights of citizenship and equality in the Constitution through the 14th amendment.
