Mark Levin was talking about this on his show yesterday. He was saying there were lots of reasons the 12 R senators voted in favor of ending the national emergency. Some are funded by the open borders Koch Brothers, some are worried the wall money will take money away from projects in their state, and other have business dealings with mexico in their states. That's just 3 of the reasons, the Koch brothers I think is the main one though because they are notoriously open border scum bags.
