The Jackson, Michigan, campaign office of Rep. Tim Walberg (R) was vandalized on Tuesday night, while activists claiming to be affiliated with the far-left abortion advocacy group Jane’s Revenge said they were behind an attack on the broader building.

Images of the damage released by Walberg’s campaign show a smashed window, a damaged door, and broken glass littered on the ground inside and outside of the office. Additionally, a sign appeared to have been defaced with “JANE’S REVENGE” spray-painted in pink.
