"I am writing to resign from my position as Special Advisor to the President of the United States," Atlas said, thanking him for "the honor and privilege to serve on behalf of the American people." "I worked hard with a singular focus—to save lives and help Americans through this pandemic," Atlas wrote, adding that he "always relied on the latest science and evidence, without any political consideration or influence."

"As time went on, like all scientists and health policy scholars, I learned new information and synthesized the latest data from around the world, all in an effort to provide you with the best information to serve the greater public good," Atlas wrote. "But, perhaps more than anything, my advice was always focused on minimizing all the harms from both the pandemic and the structural policies themselves, especially to the working class and the poor."
