After taking over the Interior Department last year, Secretary Ryan Zinke Ryan Keith ZinkeTrump extends Florida offshore drilling pause, expands it to Georgia, South Carolina Conspicuous by their absence from the Republican Convention Trump flails as audience dwindles and ratings plummet MORE decided to revive an arcane, military flag-flying ritual at the department, The Washington Post reported in October.

The process involves a security staffer going up to the roof and hoisting a special "secretarial flag," which is emblazoned with the agency’s bison seal and flanked by seven white stars, whenever Zinke enters the building. The flag then comes down whenever Zinke leaves.

“I had no idea there was a secretarial flag,” Jewell told HuffPost. “And if I had known there was a flag the last thing I would have done was to ever fly it.”

Zinke, a former Montana congressman and Navy SEAL, took some criticism for restoring the ritual, a part of which — flying the deputy secretary's flag — violates agency rules for displaying and flying flags, according to HuffPost.

A spokeswoman called it “a major sign of transparency” at the time in a statement to the Washington Post.

“Ryan Zinke is proud and honored to lead the Department of the Interior, and is restoring honor and tradition to the department, whether it’s flying the flag when he is in garrison or restoring traditional access to public lands,” she told the publication.

Jewell said anyone who leads Interior should work at “creating an inclusive atmosphere, making people feel how important they are to the American people.”
