Van Jones on Saturday's 50 State Protest for Labor Rights

(Reuters) - Tens of thousands of demonstrators were expected to take to the streets of the Wisconsin state Capitol later on Saturday as protests against a Republican plan to curb the power of public sector unions entered their third weekend. 

Labor groups also planned for large demonstrations in every state capital in the nation on Saturday to show solidarity with Wisconsin in fighting the proposal they see as trying to break the union movement. 

Organizers and law enforcement were expecting another huge turnout in Madison, rivaling the estimated crowd of 50,000 last Saturday which was the largest protest since the demonstrations began. 

But demonstrators will have to brave frigid temperatures in Madison, where the high is forecast to reach only 19 degrees Fahrenheit on Saturday.
