A supporter of Venezuela's President Hugo Chavez holds up a poster of Chavez behind people waiting in line to enter a military hospital in Caracas, Venezuela, Wednesday, Feb. 20, 2013. Chavez is allegedly receiving treatment at this hospital, but the people in line are there for routine hospital visits unrelated to the president. Chavez's sudden return to Venezuela after more than two months of cancer treatments in Cuba has fanned speculation that the president could be preparing to relinquish power and make way for a successor and a new election.
