A Texas prison inmate serving time in Amarillo's Clements unit is apparently unhappy with Governor Perry.
The inmate reportedly sent white powder in a threatening letter to the governor.
That caused officials today to shutdown the state office building where the governor's mail is processed.
Officials tell us the power is nonhazardous but was sent off for further testing.
A spokeswoman for the Texas Department of Public Safety declined to release the inmate's name.
