Answer: James Abraham Garfield
Explanation:
James Abraham Garfield was the 20th President of the United States of America. He was the President from 4th of March 1881 to 19th of September 1881.
He was shot in his back at the Baltimore and Potomac station, by assassin Charles Guiteau on the 2nd of July 1881. Although he survived the initial shooting, he died after eleven weeks.

The Mexican-American War and the 1848 Treaty of Guadalupe Hidalgo, forced onto the remnant Mexican government, drew some criticism in the U.S. for their casualties, monetary cost, and heavy-handedness. Furthermore, the question of how to treat the new acquisitions also intensified the debate over slavery and in many ways inflamed it, as potential westward expansion of the institution took an increasingly central and heated theme in national debates preceding the American Civil War.
