A top House Democrat on Wednesday asked the White House for details about private charter jet trips that counselor to the president Kellyanne Conway took with former health and human services secretary Tom Price, who resigned last week amid disclosures about his widespread use of chartered flights for government business.

Conway took several trips with Price on charter jets for appearances on the opioid epidemic, Politico reported. In a letter to the White House, Rep. Elijah E. Cummings (D-Md.), the ranking member on the House Oversight and Government Reform Committee, asked Conway to provide documentation of all noncommercial flights she has taken, including where they left from and landed, a list of passengers and the  full cost of each flight, in addition to her seat.

Before his recent resignation, Price announced that he would reimburse taxpayers for the cost of “his share of the travel,” which came to just less than $52,000.

Cummings asked Conway whether  she also plans to reimburse the government for the cost of her seat on any of them.

“In contrast to Secretary Price, you have been silent about your actions, you have made no commitments to stop traveling on private flights, and you have not assured the American taxpayers that they will not have to pay a dime for your seat on these flights,” Cummings wrote.

A White House spokesman did not immediately respond to a request for comment on Cummings’s letter.

Cummings and Oversight Committee Chairman Trey Gowdy (R-S.C.) have also demanded records from the White House on air travel for executive officials since Trump’s inauguration, saying that official travel “by no means should include personal use.”

In a separate missive to Treasury Secretary Steven Mnuchin, Cummings asked for a copy of Price’s reimbursement check.
