"He has some misguided decisions that he is making that he is expecting us to just kind of sit down and shut up and accept, and many of us are not going to sit down and shut up. We're going to say, 'No, we do not like this'," she said on "FOX News Sunday" following her appearance.
"When he's up there at a -- I'll call it a lectern -- when he is up there and he is telling us, basically, 'I know best. My people here in the White House know best, and we are going to tell you that yes, you do want this essentially nationalized health care system.' And we're saying, 'No, we don't.' And the messages are not being received by Barack Obama. So I think instead of lecturing, he needs to stop and he needs to listen on health care issues, on national security."
Palin said incurring "greater and greater debt" was "immoral."
"I believe is immoral because we're handing the bill to our children. They're going to have to pay for our needs and some of our wants today, and I think that that is unfair," she said.
President Obama criticized Republicans for cosponsoring a bill to set up a bipartisan deficit reduction commission and later deciding not to vote for it, but said he was willing to work with Republicans on reducing the deficit.
"If Democrats and Republicans come together in a sensible way, put everything on the table, not trying to position themselves politically ahead of time, then there's no reason why we can't start putting in place some serious measures that will start driving the deficit down long-term. The biggest thing, the most important thing that we can do on deficits," he said, "is to get a health reform package passed."
Palin also criticized the president for being weak on national security, by allowing 9/11 mastermind Khalid Sheikh Mohammad to be tried in federal court in the U.S. versus a military tribunal, and for allowing the failed Christmas Day bomber Umar Farouq Abdulmutallab to be read his Miranda rights 15 minutes after being arrested.
"This, like a mere law enforcement matter, places our country at grave risk, because that's not how radical Islamic extremists are looking at this. They know we're at war. And to win that war, we need a commander in chief, not a professor of law standing at the lectern," Palin said Saturday.
The president defended both decisions.
"I think that the most important thing for the public to understand is we're not handling any of these cases any different than the Bush administration handled them, all through 9/11. They prosecuted 190 folks in these Article III courts, got convictions, and those folks are in maximum security prisons right now, and there have been no escapes. And it is a virtue of our system that we should be proud of," he said.
"Keep in mind Richard Reid was read his Miranda rights five minutes after he was arrested under the previous administration. Some of the same critics of our approach have been employing this policy for years," he said.
While Obama said he had not ruled out New York City as a venue for Mohammad to be tried, he said the process of reading suspected terrorists their Miranda rights "should be reviewed."
