Call Congress
Your elected representatives are only responsible to their constituents. Calling from outside their district or state is not impactful.
HOWEVER, they also monitor Social Media which is not location specific. Use it to voice your concerns from outside their districts.
Call the U.S. Capitol Switchboard at (202) 224-3121 and ask for your Senator’s or Representative’s office.
You can also use an app called 5 calls to make calling Congress easier.
UPDATE: Feb 8 Congress is getting swamped with calls. Congrats to all.
“The Senate is experiencing an unusually high volume of inbound calls. External callers may receive a temporary busy signal when phoning a Senate office,” according to the memo obtained by The Associated Press.
HINT: If you find the lines busy try called their satellite office. also calling with support is also very helpful.
Use Social Media

A strength of Social media is that the Congressional staff can’t tell if a comment is from their district or state. They monitor it as a barometer of public opinion.
Unlike email, technology does not yet allow staff to separate constituent comments on social media from those coming from outside a district. Fitch said that that lack of capability doesn’t really matter much to lawmakers, who see social media more as a barometer of public opinion.
Advocacy campaigns have relied heavily on email for more than two decades, but a recent survey shows that a handful of well-conceived comments on social media aimed toward Congress may be just as effective as thousands of emails.
In a poll of House and Senate offices by the Congressional Management Foundation, three-quarters of senior staff said that between one and 30 comments on social media platforms like Facebook and Twitter were enough to grab their attention on an issue. Thirty-five percent said that fewer than 10 comments were enough.
“The contrast is shocking between Twitter volume and email volume,” CMF President and CEO Brad Fitch said.
