Another House committee on Thursday issued a subpoena for an investigation of the Trump administration — this time demanding documents related to the federal government’s lease of the historic Old Post Office building in Washington to the president’s hotel business.

The subpoena from the Transportation and Infrastructure Committee and signed by its chairman, Peter A. DeFazio, D-Ore., demands that the General Services Administration produce documents including legal records, communications between it and Trump and his children, as well as profit statements for the business, the Trump International Hotel.

The committee is investigating whether Trump’s investment in the hotel, located blocks from the White House, violates the emoluments clause of the Constitution. Trump has refused to divest from his financial interests in the building, which one of his companies began leasing in August 2013.

Trump is the sole beneficiary of a trust with the controlling interest in Trump Old Post Office LLC, according to the committee.

The committee, which has jurisdiction over federal buildings, issued the subpoena after repeatedly requesting that the GSA provide the information voluntarily.
