Here’s a quick tutorial, based on how I use congress.gov:
1. When you land at congress.gov, near the top of the page there is a search field. Usually, by default, the search is set to “Current Legislation”. The dropdown to choose this is to the left of the search field.
2. Search for your favorite cause. I searched for “EPA”. The top three results are anti-EPA bills in the House. House bills have a number that start with “H.R.”; Senate bills start with “S.”. For “fun”, I choose H.R. 694, “Stop EPA Overregulation of Rural Americans Act”. The bill is at: https://www.congress.gov/bill/
115th-congress/house-bill/694? q=%7B%22search%22%3A%5B%22epa% 22%5D%7D&r=3
3. Here’s a screenshot of the page for H.R. 694:
4. Just below the title of the bill you can see a link for “Get Alerts”. Click that link. You will have to make an account, but then it will send you an email whenever anything happens to the bill. This includes additional sponsors, modifications, amendments, committee votes, and floor votes.
