In Atlanta today, President Trump announced a "top to bottom overhaul" of the regulations that govern one of the nation's most significant environmental laws.

A federal judge has ruled that the controversial Dakota Access Pipeline must be emptied for now while the Army Corps of Engineers produces an environmental review.

In a decision posted Monday, U.S. District Judge James Boasberg said that it was clear shutting down the pipeline will cause disruption.

Cleveland Clinic anesthesiologist and study co-author Dr. Praveen Chahar said provider burnout isn’t new, but dealing with the COVID-19 pandemic has caused even more stress.

“One of the biggest reasons of increased stress in healthcare providers was a fear of getting infected themselves and a fear of infecting their loved ones,” he said.
