Andrew Johnson was the vice president for Abraham Lincoln and when he was assassinated Andrew Johnson became the new president and was the first president to be impeached. The only reason he was impeached was that he was a democrat and he wanted to take the right of being a black citizen. Another reason is that Lincoln was republican so that didn’t work out for him. He was still in office for four years but was impeached towards the end of his run, he the died a little after all this happened.
