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.

Arizona’s governor is calling for a “comprehensive and independent” investigation after a wildfire in Grand Canyon National Park torched thousands of acres and destroyed dozens of structures, including the iconic Grand Canyon Lodge.
