State lawmakers are calling on Governor Nixon to arm the National Guard following the recent attack by a gunman on two military facilities in Chattanooga, Tennessee. Governors in several other states have already issued orders to arm the National Guard. They include Texas, Florida, Louisiana, Arkansas, Indiana and Oklahoma. Republican Senator Dan Brown and GOP gubernatorial candidates Senator Mike Parson and Lt. Governor Peter Kinder are also calling for Nixon to order flags to be flown at half staff.
