TRENTON, N.J. (AP) - Eight people who work for New Jersey Gov. Chris Christie have been served subpoenas in the widening traffic scandal investigation threatening to undermine his administration.
The New Jersey Assembly confirms that subpoenas were served to Christie's chief of staff, chief counsel, communications director and other aides.
Assemblyman John Wisniewski (wiz-NOO'-skee) says 20 subpoenas were issued Thursday, though not all have reached the recipients.
The subpoenas seek documents that could shed light on who was behind a plot to create massive traffic jams and whether it was done to settle a political score.
Some people turning over text messages and emails could be called to testify later.
The scandal threatens to upend Christie's second term and derail any presidential ambitions.
Four members of his circle have lost their jobs.
