In a sharp departure from his predecessors, Health and Human Services Secretary Tom Price last week took private jets on five separate flights for official business, at a cost of tens of thousands of dollars more than commercial travel.

The secretary’s five flights, which were scheduled between Sept. 13 and Sept. 15, took him to a resort in Maine where he participated in a Q&A discussion with a health care industry CEO, and to community health centers in New Hampshire and Pennsylvania, according to internal HHS documents.

The travel by corporate-style jet comes at a time when other members of the Trump administration are under fire for travel expenditures, and breaks with the practices of Obama-era Secretaries Sylvia Matthews Burwell and Kathleen Sebelius, who flew commercially while in the continental United States.

Price, a frequent critic of federal spending who has been developing a plan for department-wide cost savings, declined to comment.
