New York Mayor Eric Adams charged on five criminal counts in 'multi ...

New York City Mayor Eric Adams has been charged with accepting illegal campaign contributions and luxury travel from Turkish nationals seeking to influence him, capping an investigation that has sent the largest US city's government into turmoil.

In a 57-page indictment on Thursday, local time, prosecutors laid out an alleged scheme stretching back to 2014 that helped to underwrite Mr Adams's 2021 mayoral campaign and showered him with free rooms at opulent hotels and meals at high-end restaurants.

In return, he pressured city officials to allow the country's new 36-storey consulate to open despite safety concerns, prosecutors said.

The Democrat faces five criminal charges and could face decades in prison if found guilty.

Mr Adams, 64, denied wrongdoing and said he would fight the charges in court, vowing not to step down.

"I will continue to do my job as mayor," he said at a news conference on Thursday, where some onlookers called on him to resign.

Türkiye's foreign ministry and president's office and its embassy in Washington had no immediate comment.

Earlier on Thursday, federal agents searched the mayor's Gracie Mansion home on Manhattan's Upper East Side, according to a Reuters witness. Around a dozen people in business attire were seen walking on the mansion's grounds with briefcases and duffel bags.

Mr Adams, a former police officer who rose to the rank of captain, is the first of the city's 110 mayors to be criminally charged while in office.

He could be removed from office by Democratic New York Governor Kathy Hochul but the process is complicated, said Pace University Law School professor Bennett Gershman.

According to the indictment, Mr Adams accepted free travel from a Turkish airline worth tens of thousands of dollars while serving as Brooklyn borough president and paid $US600 ($870) to stay two nights at a luxury suite in the St. Regis hotel in Istanbul, well below the actual cost of $US7,000 ($10,100).

Prosecutors said Adams would fly on the Turkish airline even when it was inconvenient. "You know first stop is always Istanbul," he wrote in a 2017 text message when his partner expressed that they were flying from New York to Paris through Istanbul.

For his 2021 mayoral campaign, Mr Adams disguised campaign contributions from Turkish sources by funnelling it through American citizens, the indictment said. Those funds allowed him to qualify for an additional $US10 million ($14.5 million) in public financing.

"This was a multi-year scheme to buy favour with a single New York City politician on the rise," Damian Williams, the top federal prosecutor in Manhattan, said at a news conference.

Prosecutors say Mr Adams responded to Turkish concerns.

Acting on a request by a Turkish diplomat, he pressured city safety inspectors to allow the country's new 36-storey consulate to open in time for a September 2021 visit by Turkish President Recep Tayyip Erdogan even though it would have failed a fire inspection, the indictment said.

After repeated messages about the building from Adams, a senior Fire Department official allegedly told a subordinate he would lose his job if he did not allow the consulate to open. Mr Adams notified the diplomat when the Fire Department approved the building to open later in the day, the indictment said.

"You are a true friend of Türkiye," the diplomat allegedly responded.

The 64-year-old performed other favours as well, the indictment said. 

Before serving as mayor, he allegedly cut ties with a community centre in Brooklyn that the diplomat said was affiliated with a hostile political movement, according to the indictment.

Shortly after he was inaugurated in 2022, an Adams staffer assured the diplomat that the new mayor would not make a statement on 1915 massacres of Armenians in the Ottoman Empire that Washington has called a genocide.

Mr Adams said he was aiming for a public trial to clear his name. "If it's foreign donors, I know I don't take money from foreign donors," he said.

The case is likely to complicate any bid by Mr Adams for re-election in 2025, as other Democratic politicians, including New York City comptroller Brad Lander, plan to challenge him.

US Representative Alexandria Ocasio-Cortez, a Democrat, called on Mr Adams to step down. 

But Representative Hakeem Jeffries, a Brooklyn resident who serves as the top Democrat in the House, stopped short of doing so. "I pray for the well-being of our great City," he wrote on social media.

New York has been in a state of political upheaval for the past month. Police Commissioner Edward Caban resigned on September 12, a week after FBI agents seized his phone. Days later, Mr Adams's chief legal adviser resigned.

On Wednesday, the city's public schools chief David Banks said he would retire at the end of the year, after the New York Times reported his phones were seized by federal agents.
