@chrisinbama: There was no attempt on President Theodore Roosevelt’s life will he was in office. However, there was an attempt when he decided to run again for President against William Howard Taft.
While he was campaigning in Milwaukee on his 1912 “Bull Moose” campaign on October 14, 1912, he was shot at close range by John Schrank. John Schrank was a mentally disturbed New York saloonkeeper. He shot Theodore Roosevelt in the chest and aimed the .38 caliber at Roosevelt’s head, but a bystander defected Schrank’s arm as he pulled the trigger.
Roosevelt didn’t know he was shot at first until he reached in his overcoat, after someone noticed a hole and found blood. His 50 page speech and eyeglass case saved his life slowing the bullet down as it entered his chest. The bullet was never found in his body and he healed completely without any problems.
