LITTLETON, Colo. -- A white, powdery substance sent to the suburban Denver prison where convicted Illinois Gov. Rod Blagojevich is being held wasn't hazardous.

The envelope, addressed to an inmate, was discovered Monday during routine mail screening at the Federal Correctional Institution Englewood. Prison spokesman John Sell said a hazardous materials team found that the substance wasn't dangerous.

He wouldn't say which inmate was the intended recipient.

Inmates weren't able to move around the prison while a hazardous materials team checked out the substance.

Sell said local and federal law enforcement authorities were also notified.

Blagojevich reported to the prison March 15 to begin serving a 14-year sentence.
