What was the major issue that affected Andrew Johnson's Plan?

pril 15, six weeks after Andrew Johnson was sworn in as vice president of the United States, Abraham Lincoln was assassinated. Had the assassin's plot gone as planned, Johnson, Ulysses S. Grant, and Secretary of State William Seward would have also been killed. As it turned out, co-conspirator George Atzerodt had stalked the vice president but lost his nerve at the last minute. Johnson, who was staying at the Kirkwood House hotel, rushed to Lincoln's bedside when he was told of the attack. A few hours after Lincoln's death, Chief Justice Salmon P. Chase swore Johnson in as President of the United States. Republicans were relieved that Johnson had not been killed and could provide continuity; they thought that he would be putty in their hands and would follow the dictates of Republican congressional leaders.
