DENVER (AP) - A man who plead guilty to sending a threatening letter with white powder to 1 of Sen. John McCain's Colorado campaign offices has been sentenced to 30 months in federal prison.
Authorities say Marc Harold Ramsey was an inmate at the Arapahoe County jail when he sent the letter to McCain's Centennial office days before the start of the Democratic National Convention. The letter read: "Senator McCain, If you are reading this then you are already dead!"
The white powder in the letter proved to be harmless, but it prompted the evacuation of the campaign office.
Ramsey pleaded guilty to mailing threatening communication in December after a federal grand jury indicted him.
