Michael Bastasch of the Daily Caller details infighting at the U.S. Environmental Protection Agency that involves a former John Locke Foundation Shaftesbury Society speaker.

A senior member of the Trump administration’s beachhead team at the EPA unexpectedly resigned over concerns of the “integrity” of political appointees and career employees.

David Schnare was expected to take a top post at EPA, but he abruptly resigned March 15. It wasn’t for personal reasons, but over what he called a “question of integrity.” Schnare resigned with the title of assistant deputy administrator.

“This wasn’t about me being angry or upset,” Schnare told The Daily Caller News Foundation, saying his resignation had a “much deeper story” than he was willing to disclose at the time.

Schnare didn’t go into detail, but said he would soon write about the events that led to his resignation. His comments, however, suggested infighting at EPA between transition officials, EPA Administrator Scott Pruitt’s inner circle and career employees.

“When the time comes I will name names and go into specifics, “ Schnare said. When asked if the details would be “eye-opening,” he responded: “Oh, I think so.”

While Schnare gave few details to TheDCNF aside from agency officials lacking “integrity,” InsideEPA reported he’d become “increasingly frustrated with what he described as endless infighting at the agency.”

Schnare said the White House is looking into the circumstances surrounding his resignation. The EPA did not respond to TheDCNF’s request for comment.

Reports already suggested tension between President Donald Trump’s political appointees and EPA career staff.

An unnamed career staffer told Politico that EPA employees will “fight actions they deem ill-advised or illegal by quietly providing information of what is happening inside their agencies to advocacy groups and the media.”
