Venezuela’s opposition leader Juan Guaido vowed on Tuesday to step up the pressure on President Nicolas Maduro a day after defying the threat of arrest to return to a hero’s welcome in Caracas. The 35-year-old National Assembly leader has not even been mentioned publicly by Maduro’s government since his homecoming from a tour of friendly neighbors, let alone faced arrest. “They’re drowning in contradictions, they don’t know how to respond to Venezuela’s people,” Guaido told reporters.
