Officials in the Pentagon tell NBC News that President Barack Obama is expected to call Army Chief of Staff General Martin Dempsey Thursday to tell him he's been selected to become the next Chairman of the Joint Chiefs of Staff.
Dempsey, who had two combat commands in Iraq and as CENTCOM Commander oversaw both the wars in Iraq and Afghanistan, took over as Army Chief of Staff only six weeks ago.
The White House was forced to change course over questions about the personal conduct of Joint Chiefs Vice Chairman, Marine General James Cartwright, the early frontrunner for the job. While on the road, General Cartwright reportedly permitted a drunken female military aide to sleep it off in his hotel room.
Although an investigation by the Pentagon Inspector General found no evidence of any personal relationship or wrongdoing, the incident raised doubts about Cartwright's personal judgement.
If confirmed, Dempsey would takeover from the retiring Chairman, Admiral Mike Mullen, on October 1.
