Elizabeth "Betsy" Southerland, a senior official at the Environmental Protection Agency, issued a memo Tuesday explaining her resignation from the agency, where she had worked for more than 30 years, per E&E News.

In the exit memo, released by Public Employees for Environmental Responsibility (PEER), Southerland said the EPA had been "the guiding light to make the 'right thing' happen for the greater good, including public health and safety" throughout her career. That was until President Trump and Scott Pruitt took over, whose actions Southerland says have led to "the temporary triumph of myth over truth."

Why it matters: Southerland stated that "there is no question" the administration is damaging the EPA's mission, and the long-term effects could force "our children and grandchildren" to live with increased safety risks and a degraded environment.

Key excerpts from her memo:

  • "The truth is there is NO war on coal, there is NO economic crisis caused by environmental protection, and climate change IS caused by man's activities."
  • Trump's executive order requiring agencies to repeal two regulations for every new one is "a real Sophie's choice for public health agencies like EPA."
  • "Faced with such painful choices, the best possible outcome for the American people would be regulatory paralysis where no new rules are released so that existing protections remain in place."
  • "It may take a few years and even an environmental disaster, but I am confident that Congress and the courts will eventually restore all the environmental protections repealed by this administration because the majority of the American people recognize that this protection of public health and safety is right and it is just."
