The former Democratic vice presidential nominee said in an interview with The Associated Press on Thursday that his decision is final.
"Period. Full stop," Kaine said.
The 58-year-old said he wants to serve in the upper chamber for as long as he's healthy and the voters of Virginia, and his wife, allow him.
Kaine said that as a member of the Senate's Democratic minority he will work as a key check on President-elect Donald Trump. Kaine says he will continue his work to expand Congress' role in voting for and declaring war.
