The White House is seeking to cut more than $2.5 billion from the annual budget of the Environmental Protection Agency — an overall reduction of more than 23 percent. The fiscal 2019 proposal released Monday marks the Trump administration’s latest attempt to shrink the reach of an agency the president once promised to reduce to “little tidbits.” The EPA already has lost hundreds of employees to  buyouts and retirements over the past year, and its staffing is now at  Reagan-era levels.

Since 2010, the Environmental Protection Agency has been embroiled in an enforcement battle with a Michigan-based company accused of modifying the state’s largest coal-fired power plant without getting federal permits for a projected rise in pollution. On Dec. 7, as the Supreme Court was considering whether to hear the case, EPA Administrator Scott Pruitt issued a memo that single-handedly reversed the agency’s position. No longer would the EPA be “second-guessing” DTE Energy’s emission projections.

Oklahoma has turned over thousands of pages of emails between former attorney general Scott Pruitt’s office and the energy industry, meeting a  deadline set by a judge who ordered the documents’ release following more than two years of effort by an advocacy organization.
