Ex-Christie aide refusing to cooperate with lawmakers' subpoena for info on lane closures

TRENTON, N.J. – A former aide to Gov. Chris Christie is invoking her right not to incriminate herself and refusing to cooperate with a subpoena from a legislative committee looking into a political retribution scandal.

The lawyer for former Deputy Chief of Staff Bridget Kelly sent a letter Monday to the committee's lawyer saying she would not comply because the information demanded "directly overlaps with a parallel federal grand jury investigation."

Christie fired Kelly last month after it was made public that she told a Port Authority of New York and New Jersey official in an email that it was "time for some traffic problems in Fort Lee."

Former Christie campaign manager Bill Stepien made a similar argument last week and is also not complying with a subpoena.
