Rock Thrown Through Glass Panel at Sanders' Seattle Headquarters

Just over two weeks ahead of Washington’s Democratic primary on March 10, the team at Bernie Sanders’ campaign headquarters in Seattle reported late on February 21 that a rock was thrown through a glass door on the premises.

According to local reports, Sander’s team didn’t know who was responsible.
