correspondent richard engel joins us live from cairo with more on this. president morsi, richard, is expected to address the nation at the top of the hour. do we have any information about what he s going to say basically trying to calm the crowds that are expected to protest? reporter: yeah. i think what he s going to say, however, is not going to calm these crowds. it is only going to make them more angry. he s probably going to set a date for a referendum on the constitution. as you said, a week ago today, president morsi gave himself extraordinary powers. he made himself more powerful than any previous egyptian presidents. more powerful than the kings of egypt, in fact. he said that his word was law. that in decree that he issued could not be overturned by the supreme court, by any court in this land. his word was god s word. and people here became very upset. they couldn t exactly figure out what he was trying to do. now it s become clear what he was trying to do.
