Which of the following were actions that motivated radical Republicans to seek the impeachment of President Johnson?

President Johnson, encouraged former confederate states to reject the 14th amendment
President Johnson helped to write the new state constitution

The first action, "President Johnson, encouraged former confederate states to reject the 14th amendment," would have motivated radical Republicans to seek the impeachment of President Johnson. This is because the 14th amendment was an important piece of legislation aimed at protecting the rights of newly freed slaves and ensuring equality under the law. By encouraging states to reject it, President Johnson was seen as obstructing the progress of Reconstruction and undermining the goals of the radical Republicans.

The second action, "President Johnson helped to write the new state constitution," does not directly relate to the motivations for seeking President Johnson's impeachment. While the new state constitutions were seen as important in the Reconstruction process, they were not a central issue in the debate surrounding President Johnson's impeachment.
