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.

Federal firefighters initially tried to manage the Dragon Bravo Fire with a confine-and-contain strategy. Arizona state officials say this was a grave mistake.
