COVID-19 pandemic: Acting Secretary of the Navy Thomas Modly resigns for his handling of the COVID-19 pandemic on USS Theodore Roosevelt and the dismissal of Brett Crozier.

Thomas B. Modly is an American businessman and former government official who served as acting United States Secretary of the Navy from November 24, 2019, to April 7, 2020. He resigned as acting Secretary in the wake of his firing and berating Brett Crozier, the captain of the aircraft carrier USS Theodore Roosevelt, for allegedly going outside his chain of command in calling for help to deal with a COVID-19 outbreak onboard. Later, Modly traveled to the ship at port in Guam, where he addressed the crew in a manner that was perceived as disrespectful. He was subsequently widely criticized, and submitted a letter of resignation.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the cause of the COVID-19 pandemic, was detected on the aircraft carrier USS Theodore Roosevelt in March 2020 while she was at sea. Affected crew members were evacuated and the ship was ordered to Guam. The captain, Brett Crozier, wanted most of the crew to be removed from the ship to prevent the spread of the disease, but his superiors were reluctant. After several days Crozier e-mailed three of his superior officers and seven other Navy Captains, outlining a plan for the ship to be largely evacuated because the virus could not be contained on board. The letter leaked to the press, and the next day the Navy ordered most of the crew to be taken ashore, but the captain was relieved of command by Acting Secretary of the Navy Thomas Modly. Modly's order was controversial, and his later speech to the crew aboard Theodore Roosevelt was criticized. Modly resigned a few days later. By mid-April hundreds of crew members including Crozier had tested positive for the virus, and one had died.

Brett Elliott Crozier is a retired captain in the United States Navy. A United States Naval Academy graduate, he became a naval aviator, first flying helicopters and then switching to fighters. After completing naval nuclear training, he served as an officer on several aircraft carriers. In spring 2020, he was commanding officer of the aircraft carrier USS Theodore Roosevelt when COVID-19 broke out among the crew. He was relieved of command by then-acting Secretary of the Navy Thomas Modly after sending a letter to Navy leaders asking that most of the crew be taken ashore which was subsequently leaked to the press. Crozier himself was also later diagnosed with the virus. He was reassigned to a shore position and retired in March 2022.
