President Donald Trump donated his first presidential paycheck to the National Park Service, Press Secretary Sean Spicer said Monday.

Secretary of the Interior Ryan Zinke and Harpers' Ferry National Park Superintendent Tyrone Brandyburg were on hand to accept the personal check for $78,333.32 on behalf of the park service.

Zinke reminded the press corps of the slogan inscribed on Yellowstone National Park's Theodore Roosevelt Arch: "For the Benefit and Enjoyment of All People."

He said that phrase is now considered the motto of his department.

The check, projected on a large screen, reflected Trump's trademark signature and his Trump Tower address, and was addressed to the department's Reston, Va. office.

Trump has been previously challenged on his promise to donate his salary to a charitable or other organization.

Spicer assured that the check accounted for "every penny that he received... since January 20 at Noon."

The National Park Service oversees much of America's federal parkland, from Acadia National Park in Maine to Hawaii Volcanoes National Park on the Big Island.
