Here is a number that is NOT BUSY that you can call.
The number is 1-877-851-6437
When it's answered, ask to speak with David Dreier's office, or whomever you choose. I have added a PDF file containing all 53 California members. Only five have signed up so far and are indicated in the PDF.
When Congressman Dreier's office answers, urge him to support HR 1207
which is now in front of the Financial Services Committee, it has 91 co-sponsors, and Congress is in session right now. You may be asked to give your name and address, which you can do if you choose. I did.
Thank you for your effort.
