The House Judiciary Committee is looking into potential violations of the U.S. Constitution after President Donald Trump floated the idea of hosting next year’s Group of Seven summit at the Trump National Doral golf resort in Miami.

Committee chairman Rep. Jerrold Nadler (D-N.Y.) and Rep. Steve Cohen (D-Tenn.), who chairs the subcommittee on the Constitution, civil rights and civil liberties, announced the investigation in a statement on Wednesday.

“The House Judiciary Committee is examining allegations of obstruction of justice, public corruption, and other abuses of power by the President as part of its impeachment investigation,” the congressmen said.

G-7 countries take turns hosting the summit, and Trump said this week he would likely select the Florida resort due to its size and location.

“We haven’t had anything that could even come close to competing with it, especially when you look at the location,” the president said from this year’s summit in the French coastal town of Biarritz.

Using his own property for the international summit could violate the Constitution’s emoluments clauses, which prohibit federal officeholders from receiving gifts or payments from governments.

“Hosting the G7 Summit at Doral implicates both the Foreign and Domestic Emoluments Clauses, because it would entail both foreign and U.S. government spending to benefit the President, the latter potentially including both federal and state expenditures,” Nadler and Cohen wrote.

They continued: “More importantly, the Doral decision reflects perhaps the first publicly known instance in which foreign governments would be required to pay President Trump’s private businesses in order to conduct business with the United States.”

Rep. Jamie Raskin (D-Md.) tweeted on Wednesday: “America is not for sale to kings & POTUS has no right to spend gov’t resources at his properties.”
