The Pentagon says the doctor named to head a review of problems at the military's mortuary in Delaware is stepping down to run for U.S. Senate.
Richard Carmona, a former U.S. surgeon general, is leaving the review panel just one day after his appointment was announced.
Pentagon press secretary George Little says Carmona notified the Defense Department on Friday that he would not be serving.
Carmona announced on Thursday that he was running for the Senate in Arizona as a Democrat. That was the same day that Defense Secretary Leon Panetta had promoted Carmona's appointment during a Pentagon briefing.
Panetta set up the panel to review the Air Force's investigation into mismanagement at the Dover Air Force Base military mortuary.
