How to sign in and submit testimony or state your support
The Washington State Legislature has guidance on how to comment on a bill.
General guidance on how to submit written testimony for House committees is published at https://app.leg.wa.gov/csi/house#. At that link, you can sign in to express support or to provide testimony. For example, to sign in for HB 1652, select the State Government & Tribal Relations committee on January 12 at 8:00 am. If you successfully followed those steps, you’ll see something like this:
Select the middle option of “I would like my position noted for the legislative record” and then complete the resulting form. You can testify or sign up in support of the bill. You must sign up at least one hour before the committee hearing is to start.
General guidance on how to submit written testimony for Senate committees is published at https://app.leg.wa.gov/csi/senate#. It works very much like the system for the House.
