Interior secretaries under the Obama administration spent close to $1 million on chartered aircraft over the last eight years, while Trump's Ryan Zinke spent just south of $73,000 on six trips since he was sworn in back in March, according to CNN.

The Interior Department submitted the records to the House Oversight and Government Reform Committee detailing flights on chartered government and private planes by former Interior secretaries Ken Salazar and Sally Jewell.

The story was first reported by the Daily Caller and followed up by CNN who obtained the same documents.

The documents were produced as the committee examines the use of private aircraft, as opposed to commercial airlines, by Cabinet-level officials under the Trump administration.

The use of private flights forced Health and Human Services Secretary Tom Price to resign in the wake of a scandal where he spent close to $1 million on private and government flights.

Zinke drew scrutiny after it was reported he took a chartered flight to speak to a professional sports team owned by a campaign contributor. The agency's inspector general is currently investigating Zinke's use of private air travel since becoming secretary.

The documents showed Obama administration secretaries spent $971,634 on 81 trips. Forty-eight of those trips were taken by Salazar, Obama's first Interior secretary, between 2010 and 2012 and at a cost of $586,196. Jewell, who followed Salazar as his successor, made 33 trips at a cost of $385,438 between 2013 and 2016.

Zinke had spent around $12,000 for chartered flights to Las Vegas and Montana. After his flight records were reported just over a week ago, Zinke called it a "a little B.S." about air travel.
