Former District 20 Delegate Heather Mizeur, who once represented Silver Spring and Takoma Park but now lives on the Eastern Shore, has told District 1 Congressman Andy Harris to resign or face a possible challenge. Mizeur wrote on Twitter, “You must resign immediately – or I will consider retiring you myself in 2022.”

Mizeur is a strong progressive who finished third in the 2014 Democratic gubernatorial primary. Harris’s district was gerrymandered to elect a Republican a decade ago but its boundaries could change in the coming redistricting. Harris made news by objecting to President-Elect Joe Biden’s electoral votes in Congress and nearly starting a brawl on the House floor.
