Envelope with white powder sent to Gov. Perry's office

Gov. Rick Perry's office received a suspicious envelope today, with a white powder in or on it, but preliminary results show the substance was not harmful, a spokeswoman for the governor said.

The envelope was similar to those that the Associated Press reported appeared this week in Alabama, Alaska, Maine, Michigan, Minnesota, Mississippi, Missouri, Montana and Rhode Island.

It wasn't immediately clear whether the Texas incident was related.
