As protests over the Iranian elections continue, the White House continues to take a cautious approach.

"Obviously we continue to have concern about what we've seen," Robert Gibbs told reporters earlier today on Air Force One. "Obviously the Iranians are looking into this, as well. We continue to be heartened by the enthusiasm of young people in Iran. But I think what's important is the concerns that we have about their nuclear weapons program, and the concern we have about their support for terror isn't any different than it was on Friday."

President Obama himself is expected to make a statement shortly when he meets with Italian Prime Minister Silvio Berlusconi in the Oval Office. A new Fox News poll finds that most Americans think he needs to take a tougher line, with 66 percent saying he has not been tough enough. Only 5 percent say he's been to tough, while 17 percent say his approach is "about right." A similar majority feels Obama needs to be tougher on North Korea as well.

The poll does find that a solid majority -- 55 percent of Americans feel that Obama's speech in Cairo was "necessary to build a bridge with Muslims." About one third, 36 percent, say it was an "inappropriate apology to the Muslim World."

The poll was conducted June 9-10 surveying 900 registered voters, and had a margin of error +/- 3 percent
