The no. 2 Democrat in the Senate posted a video message on X explaining his decision to step down after having served five terms — “longer than anyone elected to the Senate” in Illinois’ history.

“The decision of whether to run for re-election has not been easy. I truly love the job of being a United States senator,” Durbin said. “But in my heart, I know it’s time to pass the torch.”

The 80-year-old added that “a strong Democratic bench” would be “ready to serve” in his place — without naming any immediate successors — and touted his support for fellow Illinois Democratic Sen. Tammy Duckworth to replace him as Minority Leader Chuck Schumer’s second-in-command.
