A spokesman for Governor Huckabee says his office wasn`t among those that received suspicious envelopes, rigged with a match to flare when opened. Spokesman Jim Harris says the office is being cautious in handling the mail and is keeping a closer eye on correspondences. Government investigators questioned Nevada prison inmates about the letters, sent from the prison to several governors. At least eleven state leaders and Nevada`s corrections director received such letters Thursday or Friday. In three letters, the match flared, but no one has been hurt. Letters were sent to governors in Montana, New York, Texas, Massachusetts, Idaho, Nebraska, Wyoming, Colorado, Washington, Oregon and Utah. In some cases, the letters were intercepted in the mail stream before arriving at the governor`s office. The U.S. Department of Homeland Security has alerted officials in various states, including Arkansas.
