Aide's arrest sign of Maduro govt's weakness: Venezuela's Guaido

Venezuelan opposition leader Juan Guaido said the arrest of his chief of staff by intelligence agents earlier on Thursday was a sign of weakness by President Nicolas Maduro's government. "As they cannot arrest the interim president, they are looking to capture those closest to him," Guaido, who invoked the constitution to assume an interim presidency in January in a challenge to Maduro, said in a speech.
