Former Health and Human Services Secretary Tom Price, who resigned last week after it was revealed he traveled on private and military aircraft that cost taxpayers nearly $1 million, kept his promise to reimburse the government for his seats on those flights.

"HHS official tells me Tom Price did write personal check 2 Treasury prior 2 stepping down & processing of payment by HHS has been completed," ABC White House correspondent Katherine Faulders tweeted Thursday.

Shortly before resigning from his post, Price said he would reimburse the government for his own seats on private jets for domestic trips, amounting to approximately $52,000 out of the $400,000 total tab for private flights. The cost for the military flights is not included in that amount.

House Oversight and Government Reform Committee ranking member Elijah Cummings, D-Md., who also wrote a letter to Price in September requesting information regarding the private jets, sent a letter on Wednesday to Acting HHS Secretary Don Wright and Treasury Secretary Steve Mnuchin to confirm that the payments had been made.

Price's net worth is estimated around $14 million.

The Trump administration already is already making adjustments to avoid further air travel controversies. In a letter sent out to heads of federal agencies by Mick Mulvaney, director of the Office of Management and Budget, he said some top administration officials will now require prior approval from White House chief of staff John Kelly to travel on government-owned, rented, leased, or chartered aircraft.Price was just one of several Cabinet officials facing scrutiny over their use of private or military aircraft to travel instead of commercial flights, a list which also includes Mnuchin, EPA Administrator Scott Pruitt, and Interior Secretary Ryan Zinke.

Energy Secretary Rick Perry was added to that list on Thursday.
