With Venezuelan President Hugo Chavez's health in the spotlight, fiery speeches filled the halls of the country's National Assembly on Sunday.
Lawmakers unanimously approved the 58-year-old Venezuelan leader's request to travel to Cuba for cancer surgery.
But Sunday's National Assembly debate showed a sharp divide, as devastated supporters expressed solidarity with the president and opponents questioned whether Chavez was fit to govern.
Some sang, clapped and cried as they showed support for Chavez, who announced Saturday night that his cancer had returned and said he needed to return to Havana for surgery.
"We are going to speak of a new battle, for Chavez's life, and for the life of the republic," said Rep. Maria Leon of Chavez's United Socialist Party of Venezuela.
Under the constitution, the National Assembly is required to approve any trip that takes the president out of the country for more than five days.
"You are facing a new fight, and we face it with you. ... It is difficult to find words to say how much we love you," Leon said.
Opposition lawmakers said they would approve Chavez's request, but pushed for Vice President Nicolas Maduro to take over while the Venezuelan leader is in Cuba.
"The constitution says the nation's capital is in Caracas, not in Havana. ... No act can be dictated outside the national territory," said Rep. Hiram Gaviria.
Members of Chavez's party said such a move was unnecessary, and accused opponents of trying to politicize the president's illness.
"In Cuba, in China, in Europe, he is our president, wherever he is," Rep. Gladys Requena said.
On Saturday, Chavez said he wanted Maduro to replace him if "something were to happen that would incapacitate me."
If the president dies, Venezuela's Constitution specifies that the vice president assumes the presidency until new elections can be held.
Chavez called for voters to take things a step further.
"My firm opinion, as clear as the full moon -- irrevocable, absolute, total -- is ... that you elect Nicolas Maduro as president," Chavez said, waving a copy of the Venezuelan Constitution as he spoke. "I ask this of you from my heart. He is one of the young leaders with the greatest ability to continue, if I cannot."
It was the first time Chavez had spoken publicly about the possibility of a successor -- a shocking subject from a man who looms larger than life in Venezuela and in Latin American politics.
"This is huge. He could have said something indirectly. He could have said something like, 'We'll have to see. Let's talk about it when the time comes,'" said Javier Corrales, a professor of political science at Amherst College in Massachusetts. "He switched from being very evasive to very articulate. That must have been the result of a major change in health for the worse."
Last week, Chavez returned from Cuba after receiving medical treatment. He said doctors detected malignant cells and that he expects to undergo surgery in the coming days.
Chavez, who had surgery in 2011 to remove a cancerous tumor, has undergone further operations and radiation therapy in Cuba since then. He declared himself cancer-free in July.
Health rumors dogged Chavez on the campaign trail this year, but didn't stop him from winning re-election in October.
