It is easy to provide comments, ask questions or ask for guidance from elected officials at Federal levels.
Our Representative Scott Murphy is from our New York 20th District. He can be contacted using this email webform.
Our senior Senator is Charles Schumer (contact information). Wikipedia has a background article about him.
Our Junior Senator is Kirsten Gillibrand (email webform). Wikipedia has a background article about her. She also uses this regular form of email: kirsten_gillibrand@gillibrand.senate.gov and this format may well work for our other Federal elected officials as well - I'm not sure.
The White House also offers a web form to submit comments.
