WASHINGTON, D. C. - As he delivered his election-night concession speech after losing a bid for his fourth U.S. Senate term, the last Democrat Ohioans elected to statewide office pledged to continue fighting for the worker rights issues he’s championed throughout his career.

Democratic U.S. Sen. Sherrod Brown made clear during a farewell speech Tuesday that he does not plan to abandon his career-long fight for American workers despite suffering a bitter defeat last month in Ohio.

Sen. Sherrod Brown will leave the U.S. Senate after years in public office, but he doesn't sound like a man preparing for retirement.
