"Even as we do so it would be wrong for me to be silent about what we've seen on the television over the last few days," he said. "What I would say to those people who put so much hope and energy and optimism into the political process, I would say to them that the world is watching and inspired by their participation regardless of what the ultimate outcome of the election was." A State Department spokesman said that the United States is "deeply troubled by the reports of violence, arrests and possible voting irregularities."
"The essential right of people, to express themselves peacefully, needs to be respected. The international community remains committed to seeing Iran living up to its international responsibilities, and we will continue to use all avenues to try to convince Iran to meet its international obligations," said spokesman Ian Kelly. "Iran needs to take these allegations of misconduct or of election irregularities seriously."
"I think there are a number of factors that give us some concern about what we've seen," Gibbs said.
This weekend, Vice President Biden said that the United States was waiting and watching the events in Iran, but that the election was not "as clear cut as they make it sound."
UN Secretary General Ban Ki-Moon was also careful about commenting on election results..
"The position of me and the United Nations is that the genuine will of the Iranian people should be fully respected. I am closely following how this investigation into this election result will come out," Ki-Moon said Monday. "As of now, I have to watch all this situation, how it evolves."
President Mahmoud Ahmadinejad was declared the winner over the weekend by what was called "a large margin."
Ahmadinejad also hinted that his challenger may face punishment for continuing his fight against disputed election results, but his followers are not backing down.
Some experts are unsurprised by the claims of voter fraud. "In my view, this has never been a democracy," author and New York Times contributor Thomas Friedman said on "Good Morning America." "The whole thing is a fraud. The only reason they hold elections there is to reinforce the autocracy of the mullahs."
But what this election does reflect is the rise of moderate voices.
"I think what we are seeing is basically an upsurge of the moderates across the region," he told "GMA's" Robin Roberts. "What's new, what we're seeing is, historically, in the Middle East, the extremists went all the way and the moderates just tended to go away. And what you're seeing here is now the moderates not being willing to go away but we all always have to remember the forces of extremism there are extremely well armed, they are extremely ruthless and they are not going to give up."
According to Friedman, Ahmadinejad's government will likely put up a fight against any challenges.
"This regime in Iran will do whatever it takes to stay in power," he said.
This morning, word came of a police raid on Tehran University, where cops are said to have destroyed computers and ransacked dorm rooms. Dozens of students are also said to have been arrested.
