In a blow to President Trump, a federal judge says a lawsuit that alleges Trump's business interests violate the Constitution can proceed.
Federal District Judge Peter Messitte denied the Department of Justice's request to dismiss a case brought by the attorneys general of Maryland and the District of Columbia. The Emoluments Clause bars any president from personally profiting from his dealings with foreign governments — or even U.S. state governments.
It's the first ruling in federal court to define "emolument," which goes undefined in the U.S. Constitution's two emoluments clauses.
Messitte rejected the "cramped interpretation" of the term offered by the Justice Department. He wrote that the term applies to "any profit, gain or advantage" of value that Trump has gotten from foreign, the federal or domestic governments.
"Plaintiffs have plausibly alleged that the President has been receiving or is potentially able to receive 'emoluments' from foreign, the federal and state governments in violation of the Constitution," wrote Messitte.
The Justice Department, which represents Trump in this matter, argues the clause is not relevant to Trump's businesses. "We continue to maintain that this case should be dismissed," said Andy Reuss, a spokesman for the Justice Department.
It's the second victory for Maryland Attorney General Brian Frosh and District of Columbia Attorney General Karl Racine, who were granted legal standing to sue Trump in March. They allege their jurisdictions are economically and financially harmed as political and diplomatic officials shift their business to Trump's downtown Washington, D.C. hotel from nearby convention centers owned by those governments.
"Today's historic ruling is a substantial step forward to ensure President Trump stops violating our nation's original anti-corruption laws," said Racine. "The Constitution is clear: the president can't accept money or other benefits from foreign or domestic governments."
After opening shortly before the 2016 election, the Trump International Hotel has quickly became a favorite gathering place for President Trump's supporters, who frequently hold fundraisers and conferences there. Foreign governments have also frequently held events and put dignitaries up in the hotel.
The hotel is housed in the Old Post Office, which is owned by the federal government and leased by the Trump Organization. Legal challenges to the Trump Organization's lease on the property have not succeeded.
