The suspicious mail was reported about noon Friday. Officers arrived and worked with office staff to secure the area and ensure the safety of those present, the Rocklin Police Department said news release.

The Roseville Fire Hazmat Task Force and the FBI responded to assess the substance. Police said the FBI collected the powdery substance and took over the investigation.

Kiley said the Rocklin office remained closed until it was deemed safe.

“No one should have to worry for their safety simply because they go to work for the American people,” Kiley said in a statement.

The Police Department didn’t release any further details about the investigation.

Federal authorities were investigating letters with “suspicious substances” that were mailed to congressional and campaign offices nationwide, which was first disclosed in a message from the Senate sergeant at arms obtained Thursday by The Associated Press. The notice, sent to Senate offices, said that law enforcement officials were working to intercept any additional letters, but “it is possible that some letters may reach their destinations.”

The investigation into the suspicious mail was being conducted by the FBI, the U.S. Postal Inspection Service and the U.S. Capitol Police. Authorities were urging recipients to treat the mailings as “potentially hazardous.”
