New York City Mayor Eric Adams (D) was indicted by a grand jury on Wednesday in connection with a federal investigation, as reported by multiple sources.

The indictment against Adams is said to be sealed, creating ambiguity regarding the specific “charge or charges” that the mayor “will confront,” according to the New York Times.

“The federal investigation” against Adams has reportedly centered around “whether Adams and his campaign conspired with the Turkish government to receive illegal foreign donations,” according to the outlet.

Sources have informed the New York Post that Adams is expected to “surrender to authorities early next week.”

The announcement regarding Adams’ indictment coincides with a series of resignations and investigations involving officials from his administration. Prominent Democrats, including Rep. Alexandria Ocasio-Cortez (D-NY), New York City Councilmember Tiffany Caban, and New York City Assembly member Emily Gallagher, have publicly called for his resignation.

“I do not see how Mayor Adams can continue governing New York City,” Ocasio-Cortez wrote in a post on X on Wednesday. “The flood of resignations and vacancies are threatening gov function. Nonstop investigations will make it impossible to recruit and retain a qualified administration. For the good of the city, he should resign.”

Edward Caban, the previous police commissioner of New York City, stepped down at the start of September following the initiation of a federal investigation into the enforcement actions of the New York Police Department concerning nightclubs.

Additionally, members of Mayor Adams’ administration, including First Deputy Mayor Sheena Wright and Deputy Mayor of Public Safety Philip Banks, have experienced searches at their residences as part of an inquiry linked to Adams’ “2021 campaign.”
