I noted in my piece on Alabama senator Jeff Sessions that, in part as a result of his opposition to the 2006 immigration bill, constituents began mailing bricks to their congressmen and senators as a symbol of their support for tougher border-security measures.
A former congressional staffer passed along the image below. He says it’s the first brick his office received back in 2006.
The New York Times eventually dubbed it the “Build-a-Protest” campaign.
