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.

Edmundo González said the government made him sign a document recognizing President Nicolás Maduro as the election winner before he could flee to Spain.

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