3 top US national security officials to testify in Senate
None
Three of America's top national security officials face questions in Congress about new war powers being crafted to fight Islamic State militants. They also will be quizzed about Iran and the conflicts in Iraq and Syria.
In seeking new war powers to fight the Islamic State group, the White House must reconcile demands from Democrats who don't want another ground war with concerns of Republicans who want that option left open. On Wednesday, the Senate Foreign Relations Committee will hear from Secretary of State John Kerry, Defense Secretary Ash Carter and the chairman of the Joint Chiefs of Staff, Gen. Martin Dempsey.
