PALMDALE, Calif. (KABC) -- Hazardous materials crews responded to the Palmdale congressional office formerly belonging to ex-Rep. Katie Hill to examine an unknown powder delivered to the building.
Los Angeles County Fire Department units were called to the office on West Avenue M14 just after noon on a report of an envelope with an unknown white powder.
Several people were exposed to the powder but none are showing symptoms at this time. They will go through a decontamination process and be taken to a medical facility.
Investigators are working to determine what the white powder is.
Hill resigned last week amid allegations of an inappropriate relationship with a staffer.
