Who will be the next chairman of the Joint Chiefs of Staff? The Associated Press indicates “Two people familiar with President Barack Obama’s search” indicate he’s chosen Army Gen. Martin Dempsey. Pentagon officials asked about it declined to comment on it way or the other. Dempsey would be an interesting choice because he just started a four-year term as Army chief of staff on April 11. Navy Adm. Mike Mullen’s term ends Oct. 1.
