He was also an Associate Justice of the Supreme Court of the United States.
Born in Virginia McKinley moved with his parents to Kentucky when he was still a child. In this state, he studied law and was admitted to the bar in 1800, after which he practiced first in Frankfort and Louisville. Later he moved to Huntsville in Alabama.
Where his political career began with membership of the House of Representatives of the State, where he served from 1820 to 1822. After the death of U.S. Senator Henry H. Chambers, he was first elected to Congress in 1826, where he finished his lasting until March 3, 1831 term of office; he applied unsuccessfully for re-election.
After another session in the House of Representatives from Alabama in 1831, McKinley was a candidate in 1832 for a seat in the U.S. House of Representatives, where he represented Alabama following his successful election on 4 March 1833 to 3 March 1835. For re-election, he did not present himself; Instead, he belonged to another time the Legislature of Alabama. He was, in 1836, again the Democratic candidate for the Senate seat, which he then won; However, he took this mandate only from March 4, 1837 right up to his quick resignation on 22 April of the same year.
