Introduce yourself, ask for the name of the person who handles foreign relations, and share where you're from so your member of Congress’ staff know that you're a constituent. (“Hi, this is Joe calling from Wilmington, Delaware. Can I speak to the person in your office who handles national security?)
State the reason you are calling and the specific action you want your member of Congress to take — you think Steve Bannon's politicization of the National Security Council is frightening and you want your representative to support H.R.804, which would protect it from political influences.
Share how the call went on Facebook and Twitter and encourage your friends to reach out to their member of Congress.
