Dallas Fire-Rescue says tests came back negative on a suspicious piece of mail that caused a brief HAZMAT incident at Sen. John Cornyn's Farmers Branch office at 5001 Spring Valley. The FBI has taken over the investigation.
Cornyn's local office declined to comment, referring all questions to the senior senator's Washington office. A spokesman confirmed the situation but would not say anything further. Farmers Branch police spokesman Chad Taylor says the legal envelope in question "met criteria for his office to be suspicious."
Says Jason Evans with Dallas Fire Rescue, "Two people were exposed to the package while checking the mail, but no one has exhibited any signs or symptoms of being exposed to a hazardous substance."
The incident comes hours after the FBI reported letters containing the poison ricin were sent to President Barack Obama and Sen. Roger Wicker, a Republican of Mississippi. It's not clear whether this is in any way related to the letters sent to the president and Sen. Wicker.
In that case, however, the Associated Press reported the letters were postmarked Memphis, Tenn. and that authorities have a suspect in mind.
Farmers Branch officers remain on the street outside Cornyn's office. Other than that, the scene has cleared.
