A pair of prominent Senate Democrats said Friday they plan to introduce legislation targeting the "oppressive regime" of Venezuelan strongman Nicolás Maduro and his efforts to "steal" the July 28 election.

The U.S. government and others around the world have accused Maduro of stealing the July 28 presidential election.

Spain has denied involvement in negotiations between Venezuelan opposition leader Edmundo Gonzalez and President Nicolas Maduro's government for his flight to Spain, before which he signed a letter saying he accepted Maduro's victory in the country's July election.
