It's just proof that the article I posted is well and reliably sourced! :)
Murtha linked his statement about the Marines committing "cold blooded murder" to the briefing he had with Commandant of the Marine Corps Michael Hagee. Hagee's office subsequently denied the story but in a very mealy mouthed fashion - Patterico gives the most succinct run down: Hagees Office Responds. Fair enough. Hagee didn't want to offend his future lord and master and Murtha is a liar of epic proportions. I could understand why Hagee would try to soft kill the story.
