A Vermont judge has set a hearing Thursday morning to hear a complaint from Republican attorney general candidate Jack McMullen about incumbent Democrat Bill Sorrell’s alleged ties to a PAC that supported him during the Democratic primary.

McMullen said Sorrell violated the state law saying such PACs need to operate without any coordination with a candidate when they’re making independent expenditures on a candidate’s behalf.

McMullen points to the role of former Gov. Howard Dean, who he says both advised Sorrell about campaign strategy and appeared in pro-Sorrell ads for a PAC called the Committee for Justice and Fairness.

Both Sorrell and Dean have denied any wrongdoing in the matter.
