 “It is time to pass the torch to the next Vermonter who will carry on this work for our great state. It’s time to come home," Leahy said, speaking from the same room in Vermont's State House where he launched his first Senate campaign in 1974. 

Leahy, 81, has served eight terms in the upper chamber. He is currently the president pro tempore of the Senate, the second highest ranking position in the chamber. He also serves as chairman of the Senate Appropriations Committee and sits on the Judiciary and the Agriculture committees.
Leahy is the only Democrat from Vermont that has been elected to the Senate. 
The Democratic Senatorial Campaign Committee (DSCC) released a statement on Monday calling Leahy a "lion of the Senate." 
"Vermont is a blue state that has not elected a Republican to statewide federal office in more than 20 years, and Democrats look forward to winning this Senate seat in 2022," said Sen.
