The Tucson office of Congressman Raul Grijalva -- the southern Arizona congressman who famously called for a boycott of all things Arizona after the passage of SB 1070 -- was shut down this afternoon after staffers received a package containing what was later confirmed to be a toxic substance.
The envelope containing the substance was covered in swastikas so, as you might imagine, staffers were instantly suspicious.
About a dozen staffers work in the office, none of whom were injured.
Grijalva wasn't at the office when the package arrived and staffers were all sent home after being checked out by paramedics.
Grijalva's call for a boycott of Arizona hasn't made him too popular lately. This is the third time one of his offices has been shut down because of some sort of threat since he first called for the boycott in April.
That same month, Grijalva's Tucson and Yuma offices were closed after a guy called the Tucson office and said he was going to "blow everyone's head off."
Nobody's head was actually blown off but the offices were shut down.
Grijalva's Yuma was closed again in July after staffer noticed the front window of the office was shattered.
Police later found a bullet inside the office.

At the time, Ruben Reyes, the district director in Grijalva's Tucson office told New Times "we're not sure if the bullet and the window are related."
The Tucson Police Department, which initially responded to the call, has turned the case over to the FBI.
