JACKSON — Democratic U.S. Rep. Bennie Thompson filed qualifying papers Tuesday to seek re-election in Mississippi’s 2nd District, which includes Vicksburg, most of Jackson, Clarksdale, Greenville, Greenwood and Clinton.

Candidates have until Jan. 13 to qualify for the March 13 Democratic and Republican primaries for the state’s four U.S. House seats and one of two Senate seats.

Former Greenville Mayor Heather McTeer has said she’ll challenge Thompson in the Democratic primary. Cobby Mondale Williams of Canton plans to run in the 2nd District as an independent.

The state Democratic Party said Hattiesburg resident Michael Herrington filed Tuesday to run in 4th District, a seat held by Republican Steven Palazzo.

Albert N. Gore Jr. of Starkville filed to run as a Democrat for U.S. Senate, a seat held by Republican Roger Wicker.

A Republican list of first-day qualifiers was not available.
