Earlier this week, forces affiliated with the Maduro government broke into the homes of officials backing Guaido and threatened them with their lives. Guaido's chief of staff, Roberto Marrero, was kidnapped. In an op-ed published Friday in The Miami Herald, Vice President Mike Pence said the kidnapping was an "egregious violation of the rule of law" and was only the latest example of Maduro's "brutality and despotism."
