SEATTLE (AP) — U.S. Sen. Patty Murray’s downtown Seattle office is among a handful of congressional offices that received threatening letters containing a suspicious powdery substance that proved harmless.
The FBI and the U.S. Senate’s top law enforcement officer discussed the letters Wednesday.
Sergeant-at-Arms Terrance Gainer said in a memo to Senate offices that the letters were sent to several state and home district offices.
KOMO-TV reports that Murray spokesman Matt McAlvanah confirmed a similar letter was sent to the Democrat’s offices in Seattle’s Federal Building. Hazmat crews responded Wednesday afternoon and determined the substance was harmless.
