And the U.S president already faces a similar lawsuit that was bought in January by plaintiffs including an ethics non-profit group.
The president is already fending off similar claims in federal court in NY that he violated the foreign and domestic emoluments clauses. "The Domestic Emoluments Clause prevents individual states from competing against each other by giving the President money or other things of value", according to the Washington Post.
Lobbyists, foreign diplomats and others who might wish to curry favor with Trump have been frequenting the Trump hotel, which is unfair, the argument goes.
Of the global hotel in Washington, Racine said: "Foreign governments are spending money there in order to curry favor with the president of the United States".
Racine and Frosh said Monday that Trump has broken promises to separate himself from his business interests, noting that he receives regular updates on his company's finances. "Trump is the framers' worst-case scenario; a president who would seize office and attempt to exploit his position for personal financial gain with every governmental entity imaginable, across the United States or around the world".
"During his campaign and after his election he indicated he might end the one china policy, but on February 9 he met with the president of China, pledged to continue the one china policy, five days later China gave him trademark protection", Frosh said.
"When the president is subject to foreign influence, we have to be concerned about whether the actions he's taking - both at home and overseas - are the result of payments that he is receiving at the Trump Hotel, payments that he is receiving at Mar-a-Lago, payments that he is receiving at Trump Tower, payments that he is receiving in all of his other far-flung enterprises, and he brags about it", Maryland Attorney General Brian Frosh told The Associated Press.More news: Skipper Mithali Raj shatters world record

Trump has come under scrutiny for his alleged business dealings with American adversaries such as Russian Federation and China.
He replied that Trump's business interests "do not violate the Emoluments Clause", for reasons spelled out by the Justice Department's filing on Friday.
Trump refused to divest from his business empire before taking office, instead claiming his stake in the Trump Organization would be managed by a blind trust.
Since then, a nonprofit restaurant group, a NY hotel and restaurant owner, and a woman who books events at hotels in Washington have joined the suit as plaintiffs.
Once the federal judge permits the case to progress, the first step will be to obtain Trump's personal returns copies to determine the level of his overseas business transactions.
While a number of legal challenges have been filed accusing Trump of corruption, the latest suit is the first brought by government entities.
