MADISON (WKOW)-- Longtime Senator Herb Kohl says he'll likely stay in public service once his term expires.
But exactly what he'll be doing -- he's still not sure.
Kohl spoke at a small business in Madison Wednesday afternoon.
He announced last month that he would not run for re-election next year.
The 76-year-old spent 24 years in the senate.
He says he can't pick his favorite accomplishment.
"There are a lot of important issues I've worked on, I'm hopeful the experience I've had will be useful once my term of office expires."
The list of possible candidates to replace Kohl includes former Senator Russ Feingold and Congresswoman Tammy Baldwin on the democratic side.
And former Governor Tommy Thompson and Attorney General J.B. Van Hollen on the republican side.
