State Senator Malcolm Smith, Councilmember Dan Halloran and former Republican leaders appeared in court late last week to continue fighting federal charges.
They all pleaded not guilty in April.
Lawyers for the defendants are reportedly fighting to get some of the charges dismissed. They could not be reached for comment in time for press.
Officials said Smith, a Democrat, bribed county GOP bosses to let him run for mayor as a Republican.
Halloran is accused of setting up meetings between Smith and county leaders and negotiating payoffs. He allegedly pocketed nearly $21,000 in cash and offered up councilmember item cash in exchange for bribes, officials said.
Vincent Tabone, ex-vice chair of the Queens County Republican Party, and Joseph Savino, former chair of the Bronx County GOP, allegedly took at least $40,000 in cash bribes as part of the conspiracy, authorities said.
