New subpoenas seek to unravel NJ bridge scandal

{}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.

{}Assemblyman John Wisniewski (wiz-NOO'-skee) says 20 subpoenas were issued Thursday, though not all have reached the recipients.
