right-to-work legislation. Walker said he was not pursuing right-to-work legislation and that in his 2011 comment to Hendricks he was referring to his responsibility as governor to defend taxpayers from unions that he believed were frustrating resolution of the state's budget deficit. In announcing the proposed legislation, Walker said the Wisconsin National Guard and other state agencies were prepared to prevent disruptions in state services. He later explained that police and firefighters were excluded from the changes because he would not jeopardize public safety. Walker stated that the bill was necessary to avoid laying off thousands of state employees and that no one should be surprised by its provisions. Union leaders and Democratic legislators immediately criticized the bill, claiming Walker had never campaigned on doing away with collective bargaining rights. In a media interview a week later, Walker said he was not trying to break the public sector unions, noting that Wisconsin government employees would retain the protections of civil service laws. He said that asking employees to pay half the national average for health care benefits was a modest request. Demonstrators began protesting the proposed bill on February 14, 2011. During the sixth day of the protests, leaders of the two largest unions said publicly they were prepared to accept the financial concessions in the bill, but would not agree to the limitations of collective bargaining rights. On February 17, 2011, all 14 Democratic state senators traveled to Illinois to prevent the passage of the bill by depriving the Senate of the quorum necessary for a vote. The missing legislators said they would not return to Madison unless Walker agreed to remove the limitations on collective bargaining from the bill. Walker warned that if the budget repair bill was not passed by March 1, refinancing of a $165 million state debt would fail, and more cuts would be needed to balance the budget. By February 20, protestors had undertaken a physical occupation of the Capitol building. Protestors also covered the walls of the Capitol with thousands of homemade signs. On February 20, a union organizer participating in the protests said that the protests would continue "as long as it takes." Other union leaders called for teachers to return to work. On February 26, between 70,000 and 100,000 protested the bill in Madison. They were joined by thousands at state capitals around the nation. Appearing on Meet the Press on
