GRAND CANYON NATIONAL PARK, Ariz. — A wildfire that tore through a historic Grand Canyon lodge and raged out of control Monday had been allowed to burn for days before erupting over the weekend, raising scrutiny over the National Park Service’s decision not to aggressively attack the fire right away.

Gov. Katie Hobbs wants an independent federal investigation on the handling of the Dragon Bravo wildfire, which has burned more than 5,700 acres as of Monday.

Gov. Katie Hobbs questioned why the U.S. government decided to manage the Dragon Bravo fire, which started with a lightning strike, as a “controlled burn” during the height of the summer.
