U.S. Senator John McCain has called for President Hosni Mubarak, of Egypt, to step down amid mass protests across the country. McCain, who ran against President Obama for the presidency in 2008, made the announcement via Twitter shortly after a one-on-one meeting with the president: “Regrettably the time has come 4 Pres. Mubarak 2 step down & relinquish power. It’s in the best interest of Egypt, its people & its military," he said. The tweet came after days of peaceful protests turned violent, as pro-Mubarak demonstrators were unleashed upon pro-democracy protestors in Tahrir Square. President Obama's call for a swift transition reportedly enraged the leadership in Cairo, who saw it as a repudiation to Mubarak's call for an orderly transition.
