Venezuelan political leader Juan Guaido was taken out of his car and briefly detained on Sunday, according to the Associated Press and other reports. In video posted to social media, an SUV appears to be intercepted on a highway, which Guaidio was purportedly taking to get to an anti-government rally. Guaidio, who heads the country’s opposition-controlled Congress, could not be clearly identified from the video. But Guaidio's detention was confirmed by his wife and own Twitter account, per AP. One of his colleagues told the news agency that Guaidio had been released. The politician has helmed an increasingly contentious standoff with socialist President Nicolas Maduro, as opponents want to push Maduro out of office. Guaidio reportedly said at a Friday rally that he is ready to serve as interim president.
