Update: Gov. Brewer went on an unannounced trip to Afghanistan. 

Someone check the Appalachian Trail, there's another governor on the loose.

Arizona Gov. Jan Brewer (R) is out of state on official business all week, according to her staff, but they're not saying where, the Associated Press reports.

Brewer spokesman Matthew Benson said in a brief email to The Associated Press that Brewer was unavailable to participate in the general election canvass Monday morning because she was out of the state on official business.

"That is all I can disclose at this time," Benson added.

He later reiterated that during a brief phone interview during which he said he could not respond to several questions about Brewer's whereabouts.

Arizona Secretary of State Ken Bennett is serving as acting governor until Brewer returns.

As the AP notes, Bennett grabbed headlines last year while filling in for the governor. He removed the chairwoman of the state's redistricting commission, an ouster later overturned by the Arizona Supreme Court.
