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.

U.S. Senators Ruben Gallego and Mark Kelly joined Gov. Katie Hobbs in calling on U.S. Interior Secretary Doug Burgum to launch a full investigation into the fire management decisions that led to the loss of the irreplaceable Grand Canyon Lodge on July 12.

The fire that burned for days on the North Rim of Grand Canyon before it became uncontrollable was "expertly handled," the National Park Service said.
