Egypt's newly elected president, Mohamed Morsi, joined Friday protest on June 29 in Tahrir square. Thousands had gathered in Tahrir square to protest against the complementary constitutional declaration issued by the Supreme Council of Armed Forces, known as SCAF, which limits the president's powers and gives SCAF wide range of legislative and executive powers. Morsi addressed the protesters in Tahrir square and swore a symbolic oath before the crowd, telling them they were the source of all authority. Morsi will officially be sworn in on Saturday. He made a historic speech. He sent a reassurance message to all Egyptians and promised to protect the rights of all citizens. He also stressed that he will not give up on any of the powers given to the president in reference to the constitutional declaration issued by SCAF. He also pledged to work for the release of civilians detained by the military, and to seek justice for those killed and injured during the revolution. Protesters were satisfied with the speech and there was a positive feedback. Protesters chanted "Free revolutionaries, we'll continue the path" and "Down, down with Military rule". The presidential guard had arrived before Morsi to secure him while delivering the speech.
