Opposition lawmakers hold up banners showing photos of Mexico's president-elect Enrique Pena Nieto, saying "Purchased Presidency" during the presidential swearing in ceremony at the National Congress in Mexico City, Saturday Dec. 1, 2012. Pena Nieto became Mexico's new president on Saturday, bringing the old ruling party back to power after a 12-year hiatus amid protests inside and outside the congressional chamber where he swore to protect the constitution and laws of the land.
