Politicians spoke out on social media Tuesday after it was revealed that Sen. Orrin Hatch, R-Utah, is not planning to run for reelection.

A video announcement about the decision was posted on Twitter.

“I’ve always been a fighter,” Hatch, 83, said in the clip. “I was an amateur boxer in my youth and I’ve brought that fighting spirit with me to Washington. But a good fighter knows when to hang up the gloves, and for me, that time is soon approaching.”

Hatch, the chairman of the Senate Finance Committee, said he’s chosen to “retire at the end of this term.”
