Prosecutors charged a jail inmate Friday with sending a threatening letter and white powder to a Colorado campaign office for GOP presidential candidate John McCain.
Tests showed the white powder wasn't anthrax or any other lethal substance, but authorities had not determined what it was.
Prosecutors said Marc Harold Ramsey, 39, sent a letter to McCain's office in the south Denver suburb of Centennial reading, “If you are reading this, then you are already dead!”
The letter was signed Akeem Ramsey El, but the return address on the envelope had Ramsey's name and “Arapahoe County Detention Facility.”

Ramsey, 39, is in the Arapahoe County jail awaiting trial on a charges of menacing, harassment and assaulting a peace officer.
U.S. Attorney Troy Eid said Ramsey told investigators he wrote the letter to express his views about the U.S. government.
“A death threat by no means is a legitimate form of political expression,” Eid said.
The Secret Service – which provides protection to the candidates – said a separate scare triggered by a letter sent to a McCain campaign office in Manchester, N.H., was a false alarm.
When the New Hampshire office received a letter with a Denver postmark, officials became concerned because they had heard about the Colorado letter.
