Nearly 200 Democratic lawmakers have joined forces to file a legal case against President Donald Trump over receipt of payments from foreign governments via his businesses.

The plaintiffs accuse President Trump of violating the Constitution’s emoluments clause, prohibiting receipt of gifts without congressional approval.

They say this is the largest number of legislators ever to sue a US president.

State officials and private businesses are suing Donald Trump in similar cases.

The attorneys general of Maryland and the District of Columbia announced their lawsuit on June 12.

The White House has denied their allegations.

Spokesman Sean Spicer said that “partisan politics” could be behind the lawsuit of the attorneys general.

The justice department declined to comment on the latest suit by legislators, but has said previously it is unconstitutional to sue the president in his private capacity.

At least 30 senators and 166 representatives are involved.

They say President Trump has not sought congressional approval for any payments received by his businesses from foreign governments since he took office.

“President Trump has conflicts of interest in at least 25 countries, and it appears he’s using his presidency to maximize his profits,” said Representative John Conyers, quoted by Reuters.

“We do this not out of any sense of pleasure or partisanship, but because President Trump has left us with no other option.”

Senator Richard Blumenthal said: “The president’s failure to tell us about these emoluments… mean that we cannot do our job. We cannot consent to what we don’t know. He’s interfering with our constitutional duty.”

Donald Trump’s worldwide organization includes more than 500 business entities, including hotels, golf courses and apartment buildings, many of which have done business with foreign governments.

Since taking office in January, Donald Trump has turned day-to-day control of his real estate empire and other assets over to a trust managed by his adult sons.

However, he has not sold them off as critics said he should do in order to avoid conflicts of interest.

A non-governmental organization, Citizens for Responsibility and Ethics in Washington (CREW), lodged a similar legal action in January.

Donald Trump’s lawyers have argued the emoluments clause is intended only to stop federal officials from accepting a special consideration or gift from a foreign power and does not apply to payments such as a bill for a hotel room.
