President Obama tells our sister network Telemundo that the U.S. is waiting to see how Egypt responds. "I don't think that-- we would consider them an ally. But we don't consider them an enemy. They-- they are a new government that is trying to find its way."
Protesters are angry over a video they say insults the Prophet Muhammad. Our embassy in Cairo called the video "misguided."
Mitt Romney and Paul Ryan criticized that response: "Instead when our grounds are being attacked and being breached, that the first response of the United States must be outrage," said Mitt Romney, (R) Presidential Nominee.
