Donald Trump's presidency will violate the government least of his hotel in Washington, DC, according to two law professors and former federal officials who have warned about an upcoming conflict of interest.

The Trump International Hotel Washington, DC, which opened during his presidential campaign, is located in the historic Old Post Office Pavilion on Pennsylvania Avenue - less than a mile away from the White House.

The Trump Organization obtained a 60-year-lease, $180 million in 2013, which bars elected officials from having anything to do with the contract, Steven Schooner and Daniel Gordon wrote Monday in an op-ed for trade magazine Government Executive.

'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 lease states according to Schooner and Gordon, former government officials who teach law at George Washington University.

The terms of the lease mean that Trump's inauguration on January 20 will lead to 'unprecedented and intolerable conflicts of interest', they wrote.

Schooner and Gordon have both worked at the Office of Management and Budget, respectively in Bill Clinton's and Barack Obama's administrations. Both specialize in government contract law.

They believe that the General Services Administration, the government agency who agreed to lease the building to Trump Organization, should end the contract immediately.

'The terms of the contract were freely agreed to by the Trump Organization. Had President Obama or Vice President Biden (or any other elected official of the US Government) attempted to participate in the original lease agreement in 2013, we are confident that GSA would have rejected their proposal,' they wrote in Monday's op-ed.

The Trump Organization could sue if GSA breaks the contract - but Schooner believes it might be a risk worth taking.

'In the end, it's just a frigging lease,' Schooner told the Huffington Post. 'If GSA wants to terminate it tomorrow, the only thing Trump can do is sue and get money damages. That's a price worth paying.'

A GSA spokesperson told Government Executive earlier this month that the agency would 'coordinate with the president-elect's team to address any issues that may be related to the Old Post Office building'.

Trump inaugurated the hotel in Washington, DC during his presidential campaign, cutting the ribbon with his children Donald Jr, Eric, Tiffany and Ivanka and with his wife Melania.

He once said he would put his business in a blind trust to avoid conflicts of interests as president, but has since decided that his adult children would run the company.
