The correct answer is: Congress accused president Johnson of abusing his presidential powers, and Johnson thought that congress overstepped its authority in carrying out radical reconstruction.

Explanation:

After Abraham Lincoln was killed, in 1865, Andrew Johnson was elected as the president of the U. S. Shortly after that, he started with his plan for the South's reconstruction. When the Congress met to evaluate the situation, one of the assumptions was that President Johnson was overstepping his boundaries, as the Republicans thought the reconstruction of the South was not his job, but the job of the Congress.

Congress made a plan to distribute the land between freedmen and create schools, but this bill was vetoed by President Johnson. He said this was a violation of the separation of powers, as he considered it expensive and unconstitutional.
