There's a campaign to send bricks to various legislators as a symbol of the border wall. It's certainly a good way to get their attention, but I would perhaps prefer that people spend their time and money attempting to discredit those legislators instead. Be that as it may, the picture above is of bricks in the office of Senator Mel Martinez. Amie Parnes of the Naples News discusses the campaign here in the falsely-titled "Immigration foes throwing bricks at Sen. Mel Martinez", although she doesn't understand the issue very well.
