The Ken Lewis campaign plans to announce a major endorsement by former Durham mayor and state Sen. Wib Gulley today at 4 p.m. at Golden Belt’s Labourlove Gallery, 807 E. Main St., Building 2.

Lewis, a Durham lawyer, is running for U.S. Senate. If he wins the Democratic primary, he will likely face Republican Richard Burr, who has served in the Senate since 2005. Previously, Burr spent 10 years in the U.S. House.
