What was the outcome of Johnson's impeachment proceedings?

Answer 1

The House impeached the President, but the Senate failed to remove him. The House of Representatives voted to impeach Johnson but the Senate failed----by only one vote----to win the two-thirds majority necessary in the Senate to remove Johnson from office!

Answer 2

President Andrew Johnson had a very difficult and antagonistic relationship with the so-called "Radical Republicans" in Congress. They accused him of being a drunk and said he was an ignorant man who was incapable of doing the work the presidency required. He in turn believed their attacks on him were totally partisan and without any foundation other than a desire to drive him from office because they felt he was too much of a moderate. The bickering escalated: the Radical Republicans were especially angered by some of the decisions Johnson made (such as replacing Secretary of War Edwin Stanton with Ulysses S. Grant), and they became determined to have Johnson impeached; in late February 1868, the House of Representatives did in fact impeach him.

Johnson's trial, on the grounds of "high crimes and misdemeanors" began in March 1868. Johnson was not a very popular president, but the press and some of the public believed the entire series of events was politically motivated. Johnson's trial ultimately ended with his acquittal by the senate, and he was able to complete his term.
