WASHINGTON (CBS News) - This week on "Face The Nation," we talked to top leaders on the major issues of the week: The battle at home over immigration, the execution of another American by ISIS, nuclear talks with Iran and the fate of two Americans held by North Korea.
Israeli Prime Minister Benjamin Netanyahu issued a stern warning Sunday to President Barack Obama as negotiations over Iran's nuclear program reach what could be their final stages.
"Iran is not your ally," he said. "Iran is not your friend. Iran is your enemy. It's not your partner. Iran is committed to the destruction of Israel.
Later on the program, former presidential candidate Mitt Romney weighed in on the recent election, saying President Obama "president has got to learn that he lost this last election" and take that into account as he tackles issues like immigration in the coming weeks.
"The idea of violating the principles of our constitution, which is a balance of power, checks and balances, that is something that is wrong and not to the president's benefit," Romney said, referring to executive actions on immigration that President Obama is expected to issue soon.
The former Massachusetts governor's comments were covered by the Washington Post, The Atlantic, Politico, The Hill, National Journal, National Review, Newsmax, the Washington Times, Huffington Post, the International Business Times, the New York Daily News and The Week.
Sen. Claire McCaskill, D-Mo., said that she "wasn't crazy" about the executive actions either. But she also pointed the finger at Republicans - in particular, House Speaker John Boehner -- for "[refusing] to debate one of the most complicated and difficult problems."
Sen. Mike Lee, R-Utah, said he staunchly opposes the president's immigration plan and that Republicans are ready to stand up and stop him.
"Even if [Obama] doesn't respect elections, he needs to respect the rule of law," Lee said.
Finally, we spoke to James Clapper, the Director of National Intelligence, who recently returned from a high-stakes trip to North Korea in an attempt to retrieve two Americans held prisoner there. Clapper - the nation's top spy - shared the details of his one-of-a-kind experience.
Clapper described an awkward dinner where North Korean officials criticized American foreign policy, and an encounter with a younger official that offered him a sliver of hope for the future.
But still, he said "the major message from them was their disappointment that there wasn't some offer or some big ... breakthrough," Clapper told "Face The Nation" host Bob Schieffer.
