Hoboken, N.J. Mayor Dawn Zimmer met with federal prosecutors Sunday afternoon, a day after accusing Gov. Chris Christie’s (R) allies of threatening to withhold hurricane relief money unless the mayor approved a real estate project that the governor wanted.

The New Jersey Star-Ledger reported that Zimmer, a Democrat, met with lawyers for the U.S. Attorney’s Office in Newark and provided them with documents, including a copy of her journal. The prosecutors, according to Zimmer, asked for the meeting.

“As they pursue this investigation, I will provide any requested information and testify under oath about the facts of what happened when the lieutenant governor came to Hoboken and told me that Sandy aid would be contingent on moving forward with a private development project,” Zimmer said in a statement.

The mayor has accused Lt. Gov. Kim Guadagno (R) of warning that Hoboken would not get Hurricane Sandy aid unless she quickly approved a real estate project Christie wanted. On Sunday, Zimmer defended her claims.

“I stand by my word,” Zimmer said during an appearance on CNN’s State of the Union. “They were holding our Sandy funds hostage.”
