West Conn will celebrate Constitution Day today.  It's a federal observance commemorating the formation and signing of the U.S. Constitution on September 17, 1787.  The event features a lecture by Danbury state Senator Julie Kushner at 6pm in White Hall on the midtown campus.  It's free and open to the public.  Dean of Arts and Sciences Dr Michelle Brown says the constitution is alive and applied to every citizen, so everyone should understand the authority and responsibilities Americans hold.  Kushner plans to talk about ideas of how to get involved in government.  She is a freshman lawmaker who chairs the Labor & Public Employees Committee, vice-chairs the Environment Committee, and is a member of the Housing Committee. Kushner previously served as director of Region 9A of the United Auto Workers, which covers New England, a portion of New York and Puerto Rico.
