Amid positive statements from American officials about President Hosni Mubarak's decision to relinquish his post, former GOP Senate candidate Christine O'Donnell wondered whether Iranian President Mahmoud Ahmadinejad was happy about the regime change.

"Anyone concerned Ahmadinejad is delighted by Egypt's news? Claims we're closer to a Middle East w/o Israel. Will Pres. Obama address this?" O'Donnell tweeted.

Earlier Friday, in response to 18 days of increasingly heated protests, Mubarak finally stepped down from office and handed his powers over to the Egyptian military.
