The FBI has determined a white powder contained in packages sent to members of Alaska’s congressional delegation was not a hazardous substance but a sample of concrete material.
Authorities say the offices of Alaska’s two U.S. senators and congressman had received suspicious packages through the mail Monday, prompting the evacuation of the federal building in Fairbanks and the closure of the sixth floor of an Anchorage office building.
At least two of the packages contained a white powder.
It remained unclear Tuesday why the concrete mixture was mailed to the lawmakers’ offices, but a statement from a Begich spokeswoman cited the FBI in saying “the sender had no criminal intent.”
