On this historic day an invitation from President Obama

So as we celebrate this great day, I want to invite you to add your name where it belongs: alongside mine as a co-signer of this historic legislation. Organizing for America will record the names of co-signers as a permanent commemoration of those who came together to make this moment possible — all of you who refused to give up until the dream of many generations for affordable, quality care for all Americans was finally fulfilled.

So, if you haven’t yet, please add your name as a proud health care reform co-signer today:

History, and I, are in your debt.

Barack Obama, President
