(CBS News) -- Hours after world leaders in Geneva reached an agreement with Iran over its nuclear program, Secretary of State John Kerry sat down for an interview with “Face the Nation” to address critics of the plan and defending the deal as an important “first step” to securing peace in the region.
“Everybody has a right to be skeptical because there are indications that there are people in Iran who have wanted to pursue a weapons program,” Kerry told CBS News’ Margaret Brennan, “that's why we don't take anything at face value. That's why you don't take it for granted.”
Contrary to the Iranian Foreign Minister’s claims, Kerry said Iran has no right to enrich uranium, and that the United States hasn’t ruled out military action in the region.
“[The president] has not taken that threat off the table,” Kerry said.
Rep. Steny Hoyer, the number two Democrat in the House of Representatives, appearing later in the program, called the Iran nuclear agreement a “marginal improvement,” encouraging Congress to move forward with the sanctions bill already passed by the House.
“We don’t trust Iran,” Hoyer told host Bob Schieffer. “We need to verify that they are in fact are going to do what they say they’re going to do.”
Republican Rep. Kevin McCarthy, appearing after Hoyer, agreed that the Senate should continue with the sanctions bill.
"We're dealing with Iran, one of the top supporters of terrorism around the world," McCarthy said. "We are providing them resources and money and we should not take this lightly. We have to have a full dismantling if we want the world to be safer."
Turning to domestic issues, Reps. Hoyer and McCarthy weighed in on the troubled Obamacare rollout.
“I do not believe you can fix this law to lower the cost and increase access,” said House Majority Whip Kevin McCarthy, “We have to scrap it and start anew and get a bipartisan consensus that actually puts the patient first and lowers the premiums.”
Rep. Hoyer dismissed the notion that the problems plaguing Obamacare were enough to force congress to “start over.”
“I don’t think Obamacare has failed,” he said, “access to Obamacare has failed.”
The Maryland Democrat admitted he was not satisfied with the Obamacare website.
“The process has been terrible. And we're all very disappointed, those of us who support the Affordable Care Act.” Read more the Minority Whip’s take on the problems facing Obamacare at The Wall Street Journal, The Hill, Politico and Real Clear Politics.
