DeKalb County Sheriff Tom Brown, who has served sine 2001, will step down in early March to pursue a Congressional bid.

Brown recently opened headquarters in Tucker for run against U.S. Rep. Hank Johnson, a Lithonia Democrat now in his fourth term in office.

Qualifying for state and federal races will be held in DeKalb between March 3 and 7, and other candidates are expected to come forward in the Congressional race.
