Urgent · Action needed now<br>AB2047 passed the Assembly. Now the Senate decides.

The bill cleared the full Assembly and has moved to the State Senate, where it goes first to the Judiciary and Public Safety committees. These members decide whether AB2047 advances - so these are exactly the people who need to hear from you now. Below is every member of both committees, with a direct phone line and email for each.

Email every committee member

One email can reach every committee office plus the legislative staff who handle these bills. Copy the full list, paste it into the BCC field so offices don't see each other's addresses, and send a single message.

📋<br>Copy all emails

Suggested subject: Please vote NO on AB 2047 . Tip: paste into BCC , not To.

Better yet, call their offices

A ringing phone in a Capitol office is hard to ignore - calls often carry more weight than email. No script needed: give your name, say you're a Californian, and urge a NO vote on AB 2047 . Tap any number to call that office directly.

Write in your own words - here are the points that matter

Personal letters from real Californians carry far more weight than form letters. Pick the points that matter to you and tell them why, in your voice:

The bill does not make anyone safer.

The bill was rushed and now contradicts itself - after 33 amendments, its manufacturer mandate points to certification rules the same amendment deleted.

The required technology is not possible - 3D printers read code, not intent; they cannot tell what a shape is for.

The bill requires software that, if it could exist, would violate the First Amendment.

It disrupts education at every level - K-12, CTE, libraries, community colleges, and universities.

It breaks open-source 3D printing , which most classroom printers rely on, by demanding open firmware be as locked-down as proprietary firmware.

California small businesses bear the burden - they must source or build firearm-blocking software that does not exist just to keep selling printers.

The penalties hit the wrong people - the $25,000-per-violation fines fall on schools, makers, and small businesses, while bad actors route around the law.

The exemptions are undefined - the bill exempts printers sold "exclusively" to entertainment studios, but no printer is built for one industry, leaving makers and cosplayers out.

Engage<br>Things you can do today.

Legislators weigh messages from the people they represent most of all - so if you live in California, your own Senator and Assembly Member need to hear from you. But every informed voice adds to the pressure, in California and beyond. Each of these takes five minutes or less. Do one today. Do all three this week.

Contact your representative<br>Find your own State Senator and Assembly Member, and tell them to oppose AB2047. Representatives listen hardest to the constituents they answer to - and the more informed Californians who speak up, the louder that message lands. Phone calls beat emails. Two minutes, big impact.
