New York City Mayor Eric Adams was reportedly subpoenaed as part of a federal investigation into corruption and unlawful campaign donations related to his 2021 campaign.

Three subpoenas were served in July, The New York Times reported. They seek an array of materials such as texts, documents and other communications, and reportedly seek information on the travel of Adams, his aides and others, as well as fundraising activities.

Specifically, the subpoenas were issued to Adams, City Hall and Adams' mayoral campaign, according to CNN. The subpoena to City Hall seeks information including about his travel to Turkey.

Investigators are looking into whether Adams and his campaign schemed with the Turkish government to receive unlawful foreign donations, as well as free flight upgrades Adams received from Turkish Airlines. It's also looking into whether the fire department was pushed to authorize a new skyscraper consulate for the country in Manhattan facing safety questions, the Times reported.

Fabien Levy, a spokesperson for Adams, told CNN that Adams expects everyone to cooperate and "swiftly bring this investigation to a close."

“As a former member of law enforcement, the mayor has been clear over the last nine months that he will cooperate with any investigation underway. Nothing has changed,” Levy said.
