>> The Senate holds an open hearing Monday on whether Congress needs to reauthorize the use of American military force in the fight against terror. Secretary of State Rex Tillerson and Defence Secretary James Mattice, set to weigh in on that question publicly for the first time, at a hearing before the Senate Foreign Relations Committee.
The debate over the use of force has been reignited by the deaths of four US soldiers in an ambush earlier this month, while on a counterterrorism mission in the nation of Niger. That operation, and many others like it, fall under a 16-year-old Authorization for the Use of Military Force or AUMF.
The measure passed by Congress in 2001 after the 9/11 attacks. The AUMF was intended for the use of force against Al Qaeda and the Taliban. Some in Congress argue it does not offer a solid enough legal basis to take on threats such as Islamic State. Monday's hearing a first step that could lead to a new authorization to use force against future threats as the Pentagon foresees even more operations like the one in Niger, that claimed four American lives.
