DENVER (Reuters) – A suburban Denver campaign office of U.S. presidential candidate John McCain was evacuated on Thursday, and several people went to a hospital, after receiving an envelope containing a threatening letter and an unidentified white powder, a campaign spokesman said.

The letter arrived in the mail in the afternoon, and the campaign immediately notified local and federal law enforcement authorities, said Jeff Sadosky, a spokesman for the campaign in suburban Washington, D.C.

McCain, 71, a Republican senator from Arizona, was taking the day off from the campaign, spending the day at his home in Sedona, Arizona.

Sadosky added, “We are taking all necessary precautions,” which he said included an evacuation of the office in Centennial, Colorado, outside Denver, where dozens of people work.

He said the composition of the powder found in the envelope was not immediately known, and that he did not know to whom the parcel was addressed.

Five to 10 people who were in the office went to a nearby hospital, where “they are currently being seen by health-care professionals,” Sadosky said.

A U.S. Secret Service spokesman, Malcolm Wiley, said the envelope sent to the McCain campaign office was opened by a campaign staffer there, and that an FBI hazardous materials team was dispatched to the scene, along with Secret Service personnel and local authorities.

CBS4-Denver has a couple of photos of the Hazmat crews that are on the scene.

9 News reports that the McCain camp is saying another powder-filled letter was rec’d at another McCain campaign office:

The McCain campaign says there was a second envelope with a white powder and threatening letter in it found in the McCain office in Manchester, New Hampshire. That letter had a return address located in Denver.
