Venezuelan vice president says Chavez 'in battle' in Cuban hospital, but also talking

Venezuela's vice president has returned from a visit with President Hugo Chavez in Cuba and says the ailing leader is in the midst of what he calls "a battle" but has also been making progress in his treatment.

Vice President Nicolas Maduro says Chavez asked questions when he visited him. Maduro expressed gratitude to Chavez's medical team during a televised meeting in Caracas on Tuesday morning.

Maduro says that Chavez is, in his words, "climbing the hill, he's advancing."

Maduro returned from Cuba along with other officials including National Assembly President Diosdado Cabello and Oil Minister Rafael Ramirez.
