Bristol County District Attorney Sam Sutter says he’ll officially announce his candidacy for Congress on Monday.
Sutter, a Democrat, will run in the redrawn 9th District.
Sutter said he plans campaign kick-off speeches in Provincetown, Falmouth, Plymouth, New Bedford and Westport.
Sutter will face U.S. Rep. Bill Keating in a Democratic primary. Keating currently represents the 10th District, which is being eliminated because of reapportionment.
Sutter was elected to the district attorney’s office in November 2006.
