MINNEAPOLIS (AP) — Dozens of Minnesota teachers are bound for Madison, Wis., for a rally to support unionized workers in Wisconsin.

The state teachers union, Education Minnesota, is sending three buses that hold about 50 people each to the rally.

Union spokesman Lonnie Hartley says the union wants to show support for teachers in Wisconsin and other unionized employees.

Education Minnesota announced the move Thursday, shortly after Wisconsin Gov. Scott Walker promised to sign a bill stripping nearly all collective bargaining rights from public employees. He did so Friday morning.
