Update 11:10 p.m.
As expected the state Senate passed the right-to-work bill late Wednesday, 17-15, after eight hours of debate, Wisconsin Public Radio's Erik Lorenzsonn reports.
Most of the protesters from earlier in the day had left the Capitol by the time of the bill's passage. Nevertheless, the few that remained chanted "Shame!" at lawmakers as they exited the Senate chambers, while some began singing protest songs in the Capitol rotunda.
