FILE - In this Dec. 18, 2007 file photo Venezuela's President Hugo Chavez, left, talks to then Foreign Minister Nicolas Maduro at the University of Uruguay in Montevideo, Uruguay. Chavez hasn't been seen or heard from since his Dec. 11 cancer surgery, and speculation has grown that his illness could be reaching its final stages. Maduro, who is now vice president and Chavez's chosen successor, is reported to have delayed plans to return home Wednesday, Jan. 2, 2013, after at least two bedside visits with Chavez. The government has provided few details but describes the ailing president's condition, after complications due to a respiratory infection, as "delicate." (AP Photo/Matilde Campodonico, File)
