Venezuelan opposition leader Juan Guaido¡¯s faltering efforts to oust President Nicolas Maduro are facing a new challenge in the form of an influence-peddling scandal that has left disillusioned Venezuelans wondering if Guaido¡¯s moment has passed.

Guaido on Sunday said the opposition-controlled congress would investigate alleged wrongdoing within its ranks after website reported that nine opposition lawmakers had advocated for a businessman linked to Maduro¡¯s government.

To a dozen Venezuelans interviewed around the country, the scandal has marked another blow to Guaido¡¯s reputation and to their hopes of seeing the back of the deeply unpopular Maduro, who has presided over a five-year economic crisis and an expanding authoritarian state.
