A former Danbury City Councilman is being nominated to fill a vacancy on the Council.  Jack Knapp, who chairs the Republican Town Committee, will have his nomination voted on tonight.  He would replace Chris Arconti who announced his resignation last month.  Arconti is moving out of Danbury and no longer eligible to serve.  RTC Vice Chair Mike Safranek says Knapp previously served in the 3rd Ward and is up to date on City issues.
