Envelope with powder sent to Minner's office

DOVER, Del. - December 17, 2008 - It was one of two letters from Texas addressed to the governor's Tatnall Building office that were intercepted Tuesday. Another envelope containing powder was received at the governor's Wilmington office last week.

Preliminary tests by the Department of Natural Resources and Environmental Control found that the white powdery substance in both envelopes is harmless, but officials plan further testing.

The FBI says governors' offices in more than 40 states and eight U.S. Embassies in Europe have gotten similar suspicious letters. All appear to be from the same source and have tested negative for any dangerous toxin or other threat.
