VIRGINIA BEACH, Va. (AP) — Officials say the offices of two Virginia congressmen received letters with a suspicious powder inside, though the material does not appear to be hazardous.

Virginia Beach Fire Battalion Chief Tim Riley says the substance found in a letter received Friday at Rep. Scott Rigell's office posed no immediate threat. A news release issued by Rigell's office says no staffers were hurt, and that the subject and intent of the letter were not known.

In Chesapeake, Rep. Randy Forbes' office also reported receiving a letter containing a powdery substance. Capt. Scott Saunders of the Chesapeake Fire Department told WTKR-TV that the material appeared to be wax residue from the envelope seal.

Neither congressman was at the offices when the letters arrived.
