On this Sunday's Face the Nation, CBS News chief political and legal correspondent Jan Crawford revealed new details on the Supreme Court's ruling of President Obama's Affordable Care Act, noting that "the discord is deep" between the justices following the decision.
"No one has any idea how it's going to be resolved but conservatives feel this sense of betrayal--that Roberts changed his mind for the wrong reasons," Crawford said.
"If he had been with the liberals from the beginning, my sources say, that would have been one thing. But to have switched his position, and relatively late in the process, infuriated conservatives."
on Face the Nation that Roberts originally sided with the conservative justices, but subsequently switched his vote in order to uphold the health care law.
Later in the show, Bob Schieffer caught up with Sen. John McCain (R-Ariz.) following his foreign policy travels through the Middle East. McCain called the U.S. leadership performance in Syria "shameful" and urged President Obama to increase aid and supply arms to rebels.
"My question to the Secretary of State and the President of the United States is, how many more have to die before we take action to help these people with other nations?" McCain said.
He also said as Syrians are "crying out for American leadership," that the U.S. should supply arms to balance the fight and establish a sanctuary within the country.
When asked about Secretary of State Hillary Clinton's comments that Syrian President Bashar al-Assad's days are numbered, McCain responded, "I believe his days are numbered, but those days could be very large in numbers and it requires American leadership."
In other foreign policy matters, McCain defended Mitt Romney's upcoming travels to Israel after recent attacks that the presumptive Republican presidential nominee should stay closer to home to address domestic issues.
"I really think it is important that Romney go to Israel, particularly, since these are the most very dangerous times," McCain said. "As you know, the talks with Iran predictably have failed, and we are facing what could be a serious crisis between Israel and Iran, so I strongly support that."
During his trip, Romney plans to meet with Israel's prime minister, Benjamin Netanyahu, and president, Shimon Peres. As a candidate, Mr. Obama traveled to Israel in the summer before the 2008 election as well.
Senate Majority Whip Dick Durbin, D-Ill., critiqued Romney's health care reform as former governor of Massachusetts, calling out similarities to Mr. Obama's Affordable Care Act.
"Let's get down to the bottom line here: Mitt Romney is the Obamacare daddy," Durbin said. "He gave birth to this baby up in Massachusetts, and now he doesn't recognize it, and can't pick out any strains in the hereditary chain there that look like anything he did in Massachusetts."
over new revelations of his offshore bank accounts and urged him to release more tax returns.
"He's the first and only candidate for the president of the United States with a Swiss bank account, with tax shelters, with tax avoidance schemes that involve so many foreign countries," Durbin said. "When it comes down to his Swiss bank account, there's just no way to explain it."
Gov. Haley Barbour (R-Miss.) said there is a lot to love about Romney in response to a recent comment made by Republican House Speaker John Boehner at a West Virginia rally.
Boehner, responding to a rally attendee's question, said, "The American people probably aren't going to fall in love with Mitt Romney. I'll tell you this, 95 percent of the people that show up to vote in November... are going to vote for or against Barack Obama."
, "There's a lot to love about Mitt Romney. But the election still's going to be a referendum on Obama's policies and the results of those policies, which are pretty poor."
"Every presidential election in the United States is a referendum on the incumbent president, if the incumbent is running, and his record," Barbour said. "But at the end of the day, Mitt Romney also has to give people something to vote for."
