How to address your fax to Mike Thompson

What to include

  • One issue per fax. Reference a specific bill number or regulation if you have one — offices sort mail by topic, and a single clear ask gets tallied accurately.
  • Your name and mailing address. House offices prioritize constituents; an address in California (ideally within District 4) signals your position should be counted as a California voter.
  • Keep it to one page. A short, specific message — what you want the representative to do, and why it matters to you — is read fully and logged.

Why fax still works for House offices

Security screening delays physical mail to Capitol Hill by weeks, and email forms bury individual messages. Fax arrives the same day with a timestamped transmission record, which is why offices — and the advocacy groups that track them — still publish fax numbers. Sending online, you get the delivery confirmation without a fax machine.
