Venezuelan Vice President Nicolas Maduro said late Monday night that he had spoken by telephone with President Hugo Chavez and that the leader is up and walking following cancer surgery in Cuba. It was the first time a top Venezuelan government official had confirmed speaking personally with Chavez since the Dec. 11 operation. Venezuelan officials have given few specifics on Chavez's condition, and have yet to offer information on his long-term prognosis, according to a report of the Associated Press. Maduro told state television station Venezolana de Television that the conversation lasted about 20 minutes. He said the president was walking and doing some recovery exercises. He added that Chavez had given him guidance on budgetary matters for 2013. "He was in a good mood," Maduro said. "He was walking, he was exercising."
