At the conclusion of President Andrew Johnson's impeachment trial:

a. A majority of senators voted to acquit.

b. Johnson resigned from office just prior to the vote.

c. Every Senate Republican voted to convict.

d. Johnson was convicted and then pardoned by the Senate.

e. Johnson was acquitted by a margin of one vote.

The correct answer is letter E

The United States of America was the first nation on the American continent to adopt the republican system. This occurred when the then Thirteen Colonies, located on the East Coast of the present USA, declared themselves independent from the English crown in 1776. The republican regime adopted by the former colonies was also presidential, that is, the maximum representative of the Executive Power would be the president the Republic, which would bring together in his person the posts of head of government and head of state; unlike, therefore, the parliamentary republic, in which the president only assumes the head of the state, while the prime minister is the head of government.

In this (presidential) system, the only recourse foreseen to remove the president from office is the opening of an impeachment process, which must have a legal basis, that is, the president must be formally accused of some crime against the responsibility of his political duties or some common crime, and political judgment and judgment in the two houses of the National Congress: the House of Representatives (deputies) and the Senate, respectively.

e. Johnson was acquitted by a margin of one vote.

Explanation:

In 1868, amid clashes and disagreements with a Republican-dominated Congress, president Andrew Johnson was impeached by the House of Representatives. 11 charges were made against him, including a violation of the Tenure of Office Act for his dismissal of war secretary E. Stanton. The Senate acquitted him by a margin of just one vote.
