Hall, 89, beat out Rep. Charles Manly Stedman (D-N.C.), the previous record holder, who was 89 years, 7 months and 25 days old in Sept. 1930 when he died.
"I’m just an old guy — lived pretty clean," Hall said according to The Associated Press. “I have no ailments. I don’t hurt anywhere. I may run again. I’ll just wait and see."
Hall was first elected to serve in the House when he was 57. Before becoming a member of the House of Representatives, Hall had served Texas's state government, was in the Navy during World War II, and helped found a bank in Rockwall County, Texas.
In 2011, Hall was named chairman of the Science, Space, and Technology Committee.
