Two mayors, rabbis and politicians are among some 30 people arrested in a major corruption and money-laundering investigation, say US authorities.
Hoboken Mayor Peter Cammarano, Secaucus Mayor Dennis Elwell, and Assemblyman Daniel Van Pelt are among those said to have been arrested in New Jersey.
Federal prosecutors said several rabbis were also detained in the states of New York and New Jersey.
Newark Mayor Cory Booker said it had been "an unbelievable morning so far".
Cars were said to be backed up four deep with suspects outside the FBI's office in Newark, New Jersey's largest city.
Jersey City deputy mayor Leona Beldini and former Jersey City council president L Harvey Smith were also reported to be among those arrested.
The nature of the charges they may face is unclear.
A news conference is scheduled for Thursday.
Synagogue raid
The news agency Associated Press spoke to a congregation member of a synagogue in Deal, a seaside borough in New Jersey, which was reportedly raided by agents from the FBI, Internal Revenue Service (IRS) and local prosecutors' office.
"Everyone was looking at each other, like, 'What's going on here?'" Mike Winnick said.
Mr Winnick said four FBI agents escorted a rabbi from the synagogue into his office and blocked the doorway.
Agents also removed several boxes from the nearby yeshiva, a school that educates the children of Sephardic Jews, AP reported.
