"Thousands of Venezuelan transport workers held a massive caravan through Caracas on Saturday, demanding the release of now former president Nicolas Maduro from US custody, marking the 35th anniversary of his first day as a Metro worker. Footage shows buses and motorcycles streaming through city streets and later taking part in a rally led by a lawmaker and the president's son, Nicolas Maduro Guerra, at the La Paz metro station. "I call on all Venezuelans from here at the Metro Caracas to unite so that we can move the country forward," said the lawmaker, urging the working class to consolidate a 'Venezuela with potential' for which Chavez and Maduro worked. Aulio Calderon, Maduro's former co-worker at the Metro, recalled his initial encounter with the Venezuelan leader and proclaimed, "We have been attentive throughout the kidnapping of our president, and we want him to return as soon as possible, along with his wife." "Those extensions are totally unfounded. The evidence is superficial, and there is nothing that could implicate him," he persisted. Craig Murray, head of the campaign for Maduro's freedom who also attended the event, remarked, "It takes heroic figures to stand up against imperialism, and Venezuela has an entire people and entire working class who stand united against imperialism. And Nicolas Maduro was a leader of that fight against imperialism." He also compared Maduro's situation with the case of activist and WikiLeaks founder Julian Assange, who in 2006 revealed leaked US documents exposing war crimes, abuses at Guantanamo and covert diplomacy. "These are parallel struggles in the same courts, and we eventually got Julian Assange out of jail. Just as we will eventually get President Maduro out of jail," he stressed. Maduro was a bus driver and union leader before joining Hugo Chavez's Bolivarian Revolution. Still, he has always maintained ties with workers and has received strong support from the working class. "
