Authorities say at least two people were taken to the hospital Tuesday after allegedly being exposed to a “white powdery substance” at Senator Ted Cruz’s office, officials said. 

The office is located in a building at 3200 SW Fwy.

Right now the 9th floor of the Phoenix Tower has been evacuated, according to authorities. 

Earlier today, the Pentagon reported at least two packages received in their mail center had tested positive for ricin.
