Interior Secretary Ryan Zinke’s $139,000 replacement doors have earned him a trip to the principal’s office.

In a letter dated March 22, House Oversight Chairman Trey Gowdy requested a briefing from Zinke following news reports surrounding the procurement of replacement doors for his office at the Interior Department.

The pricey doors revelation comes as a number of Trump administration Cabinet officials have encountered scrutiny for personal spending on the taxpayer dime. For Zinke in particular, the doors have contributed to a growing list of spending concerns, mainly surrounding the former Montana congressman’s travel transportation and security detail.

“The Committee is aware of numerous reports about the need for replacement doors at the Department and allegations of excess cost,” Gowdy wrote. “To help the Committee evaluate this matter, please provide a briefing on plans to the replace the doors.”

A response from the Interior Department was not immediately available.
