A week after the searches, police commissioner Edward Caban announced his resignation, telling officers that he did not want the investigations “to create a distraction”. About two weeks later, schools chancellor David Banks announced that he would retire at the end of the year.
Mr Adams himself insisted he would keep doing the city’s business and allow the investigations to run their course.
Over the summer, federal prosecutors subpoenaed Mr Adams, his campaign arm and City Hall, requesting information about the mayor’s schedule, his overseas travel and potential connections to the Turkish government.
Adams spent 22 years in New York City’s police department before going into politics, first as a state senator and then as Brooklyn borough president, a largely ceremonial position.
He was elected mayor in 2021, defeating a diverse field of Democrats in the primary and then easily beating Guardian Angels founder Curtis Sliwa, a Republican, in the general election.
After more than two years in office, Mr Adams’ popularity has declined. While the city has seen an increase in jobs and a drop in certain categories of crime, the administration has been preoccupied with efforts to find housing for tens of thousands of international migrants who overwhelmed the city’s homeless shelters.
There has also been a steady drip of accusations and a swirl of suspicion around people close to the mayor.
