Texas Sen. Ted Cruz, who led the effort to defund the Affordable Care Act which ended with the shutdown of the federal government, says Senate Republicans could have come to the rescue of the House GOP in the fight to end Obamacare.

But Arizona Sen. John McCain said on CNN’s State of the Union this weekend, the strategy would never have worked and the shutdown hurt Americans.

 “This has harmed the lives of millions of people and thousands of people in my state that I represent,” McCain said. “I have an obligation to them to try to prevent that from happening.”

McCain says Republicans can move past the government shutdown. He urges them to move forward with immigration reform, get a positive agenda for America, continue the fight against Obamacare, get taxes down, and address the issue of sequestration, which McCain says is devastating the military.
