A Democratic state assemblywoman who sits on the committee investigating New Jersey Gov. Chris Christie's (R) bridge scandal on Thursday called for Christie to resign.

Assemblywoman Bonnie Watson Coleman (D), one of the 12 people tasked with determining precisely what happened with the politically motivated lane closures in Fort Lee, N.J., made the comments on MSNBC.

"The governor needs to think about resigning, and he needs to take all of his friends with him," said Watson Coleman, who is also running for Congress.

When the show's host, the Rev. Al Sharpton, noted that Christie hasn't been directly implicated in the plot, Watson Coleman stood by her comments.

"I'm not saying he has done anything illegal," she said. "I'm saying it's unethical, and it is not worthy of New Jersey's citizens."

By Friday morning, the Republican leader of the assembly cried foul, saying Watson Coleman overstepped her bounds as a member of the investigative committee.

"Assemblywoman Watson Coleman caught the MSNBC fever," said Assemblyman John Bramnick. "Her call for the governor to resign may be what MSNBC wants to hear but not the people in the State of New Jersey."

Bramnick called for Watson Coleman to "withdraw her statement on resignation and wait for all the facts.”

Watson Coleman didn't immediately respond to a request for comment.
