Andrew Johnson (Democrat) becomes President of the United States after Abraham (Republican) Lincoln's death. "He had no views on race that could be considered 'unorthodox' in the South"
The congress didn't like Johnson because he kept Lincoln's cabinet. Meanwhile, Johnson issues his plan for the Reconstruction, the Amnesty while Congress is not in session.
Three days after vetoing a bill and one day after Congress overrides the veto, Johnson gives a speech an George Washington's birthday. He called out to specific Radical Republicans, by name, and called them "dis-unionists," accusing them to be disloyal.
You're a dis-unionists, and you're a dis-unionist!
Johnson continually vetoes all of the bills sent to him and Congress keeps overriding them! People start to get angry with him, so he travels around delivering "swing around the circle" speeches before the mid-term election.
VETO, VETO, VETO!
Johnson suspends General Ulysses S. Grant while Congress was not in session. He also dismisses Stanton after the Senate already did not consent. The Senate begins the first ever impeachment trial.
I think you should take a break!
Johnson was acquitted of all charges filed in impeachment. The President and Congress kept going back and forth with the veto and override until Johnson's end of presidency!
