U.S. Secretary of Defense Chuck Hagel walks out after a news conference at the Pentagon in Washington, January 22, 2015. Iraqi Prime Minister Haidar al-Abadi's criticism of the pace of support from the U.S.-led coalition is not helpful, Hagel said on Thursday, noting expedited U.S. arms shipments and fresh coalition efforts to support Iraq.
