Mitt Romney spokesman Kevin Madden appeared on MSNBC today and confirmed that Cofer Black, head of Blackwater USA, will stay on as an advisor to the Romney campaign:

Blackwater USA, as you may know, is a controversial military contracting group that has been asked by the Iraqi government to leave the country due to alleged violence towards innocent civilians by their mercenaries.

"Cofer Black is a renowned expert on counter-terrorism and intelligence issues. He is an advisor to this campaign — he advises the governor on a host of issues related to counter-terrorism and intelligence policy," Madden said. "All the details and all the incidents that have to do with Blackwater USA, I'm entirely unfamiliar with. I think those are questions that have to be answered outside the purview of a campaign, and instead by a private company."
