Mayor Eric Adams has arrived at court as he seeks to get bribery charges thrown out.
His attorney, Alex Spiro said the charge does not meet the federal standard of a crime.
The mayor was expected to go before Judge Dale E. Ho at 2 p.m. in Manhattan. The charge is part of a five-count indictment that was unsealed in September.
Among the charges are conspiracy, wire fraud, and that the mayor solicited illegal campaign donations from Turkish nationals. Prosecutors accuse Adams of accepting flight upgrades and travel perks totaling around $100,000.
Spiro has called the charges "extraordinarily vague," and that the flight upgrades and perks are "classic gratuities."
Prosecutors allege the mayor accepted these gifts in exchange for favors, that included fast-tracking approvals to open the Turkish Consulate even though it did not pass fire safety inspections.
On Thursday, Judge Ho denied a motion to investigate whether prosecutors leaked sensitive information to the media.
On Friday, nearly 30 organizations, including the People's Plan, sent a public letter to the New York City Campaign Finance Board calling for an investigation into the mayor's campaign finance funds. The letter calls on the CFB to use its subpoena powers to investigate alleged misconduct by his campaign involving fraudulent straw donor contributions for taxpayer funded matching funds through the city's public financing system.
Adams pleaded not guilty to all five charges on Sept. 17 and has no plans to resign. His next court appearance is Dec. 13 at 4 p.m.
