Guaido returns home

Opposition leader Juan Guaido returned to Venezuela on Tuesday after an international support-building tour and called on the people in the crisis-wracked nation to keep pushing back against President Nicolas Maduro. After his trip abroad -- including a meeting with US President Donald Trump, who threatened to "smash" Maduro's regime -- Guaido promised new sanctions "against the dictatorship" would be coming soon, and called for renewed protests.
