An advocacy group on Tuesday delivered a letter to New York Attorney General Eric Schneiderman demanding he investigate—and possibly revoke—the Trump Organization’s charter, over what the group says are conflicts of interests that violate state laws.

Now that President Donald Trump has refused to divest his assets in the company, which oversees his various real estate, hotel, and other businesses, Schneiderman should take action over its previous housing discrimination settlements, fraud allegations at its university, and other legal infractions it has allegedly committed, the letter from Free Speech for People states.

The group cited Section 1101 of New York’s Business Corporation Law, which gives the attorney general power to dissolve a business and revoke its charter if it abuses its legal authority.

“The president’s continued ownership stake in the Trump Organization poses a grave threat to our Constitution and our country,” FSFP’s legal director Ron Fein said. “Attorney General Schneiderman needs to investigate the Trump Organization’s corrupt involvement in the president’s self-enrichment scheme, and whether to dissolve the company and revoke its corporate charter.”

Schneiderman “does not need Congress to pursue this investigation,” Fein said. “He does not need the state legislature. Right now, he can use the power the people of New York have vested in him to ensure that the president is not above the law.”
