When President-elect Donald Trump takes office in January, he apparently will violate the lease for his new hotel in Washington, adding to the growing list of conflicts of interest between his business enterprises and his duties as president.

The lease for the Trump International Hotel, housed in Washington’s historic Old Post Office Pavilion, which is owned by the General Services Administration, contains a clause forbidding elected officials from involvement, according to two experts. Trump, as president, essentially would be both landlord and tenant.

In an op-ed published Monday in Government Executive magazine, Steven Schooner and Daniel Gordon, former government officials who specialize in federal contract law, recommended that GSA “immediately end the hotel lease relationship, before Trump becomes president” to avoid ethics problems.

The Post Office Lease differs from many of Mr. Trump’s other business arrangements. That’s because, in writing the contract, the federal and D.C. governments determined, in advance, that elected officials could play no role in this lease arrangement. The contract language is clear: “No … elected official of the Government of the United States … shall be admitted to any share or part of this Lease, or to any benefit that may arise therefrom…”

The language could not be any more specific or clear. Donald Trump will breach the contract on Jan. 20, when, while continuing to benefit from the lease, he will become an “elected official of the Government of the United States.”

As the clock ticks down towards President-elect Donald Trump’s Jan. 20 inauguration, the window is rapidly closing on the General Services Administration’s opportunity to extricate itself from the Trump Organization’s lease of the historic Post Office Pavilion. The lease—in which Donald Trump would, in effect, be both landlord and tenant—now presents unprecedented and intolerable conflicts of interest.

As interest groups, domestic and foreign, contemplate booking rooms in the Pennsylvania Avenue landmark turned Trump International Hotel to curry favor with the President, it is easy to assume that Mr. Trump’s involvement in that lease presents challenges just as abstruse as his overseas business operations. Those overseas entanglements may, indeed, require analysis of the Constitution’s hitherto rarely discussed Emoluments Clause. Conversely, understanding and addressing the problems raised by the Trump Organization’s 60-year, $180 million lease is far simpler.

GSA need not wait for constitutional experts to weigh in, nor for Trump’s lawyers to craft a comprehensive solution to appropriately distance Mr. Trump from his entire web of business interests. The lease presents relatively straightforward government contracting issues, and the contracting agency with responsibility for addressing those issues is GSA. To protect the integrity of the federal government’s procurement process, GSA must end its lease arrangement with President-elect Trump now.

When In Doubt, Read the Contract

Based on the agreement’s express terms, we believe that Trump has breached the contract. In the alternative, GSA should breach, or do whatever it takes to end, the contract. This unusual lease even envisions that the sovereign may appropriate—or effectuate a “total taking”—of the property (although we do not think such a step should be necessary).
