Who was the first US President subjected to an assassination attempt?

Andrew Jackson (March 15, 1767 – June 8, 1845) was an American soldier and statesman who served as the seventh President of the United States from 1829 to 1837. Before being elected to the presidency, Jackson gained fame as a general in the United States Army and served in both houses of Congress. As president, Jackson sought to advance the rights of the "common man" against a "corrupt aristocracy" and to preserve the Union.

On January 30, 1835, what is believed to be the first attempt to kill a sitting President of the United States occurred just outside the United States Capitol. When Jackson was leaving through the East Portico after the funeral of South Carolina Representative Warren R. Davis, Richard Lawrence, an unemployed house painter from England, aimed a pistol at Jackson, which misfired. Lawrence pulled out a second pistol, which also misfired. Historians believe the humid weather contributed to the double misfiring. Jackson, infuriated, attacked Lawrence with his cane. Others present, including Davy Crockett, restrained and disarmed Lawrence.
