CARACAS, Venezuela (AP) — Venezuela’s legislature on Thursday advanced an amnesty bill proposed by acting President Delcy Rodríguez that could lead to the release of hundreds of opposition leaders, journalists and human rights activists detained for political reasons. Such an amnesty is a central demand of the country's opposition and human rights organizations with backing from the United States. But the contents of the bill have not been released publicly, and rights groups have so far reacted with cautious optimism — and with demands for more information.
