Critics are taking particular issue with Trump's decision not to place his company in a blind trust.
A federal appeals court in New York on Friday ruled that a lawsuit accusing President Trump of violating the Emoluments Clause can proceed after a lower court had thrown out the case.
A panel of judges with the 2nd Circuit Court of Appeals ruled in favor of Citizens for Responsibility and Ethics in Washington (CREW), which has alleged that the president violated the constitutional clause by refusing to put his business assets in a blind trust while in office and profiting off the presidency.
"If President Trump would like to avoid the case going further and curtail the serious harms caused by his unconstitutional conduct, now would be a good time to divest from his businesses and end his violations of the Emoluments Clauses of the Constitution," Executive Director Noah Bookbinder said in a statement.
The ruling revives yet another lawsuit for Trump to defend against. He is also warding off legal challenges involving his tax returns, and his administration is facing numerous legal challenges of its policies on immigration, health care and other topics.
