CHARLOTTE, North Carolina: Donald Trump on Tuesday blasted White House rival Hillary Clinton as a liar abusing a “rigged” system, after the FBI recommended no charges be filed over her use of private email while secretary of state. “Our system is in fact rigged. It’s corrupt, it’s rigged, it’s disgraceful,” a furious Trump told a rally in Raleigh, North Carolina, just hours after Clinton appeared in the state for her debut 2016 campaign event with President Barack Obama. “She is laughing at the stupidity of our system.” Federal Bureau of Investigation director James Comey dropped a bombshell announcement earlier in the day, saying that while Clinton and her team were “extremely careless” in sending classified information via her personal email account, the agency does not support criminal prosecution. Trump, who polls show faces an uphill battle against Clinton in November, has repeatedly stressed that Clinton has sought to mask her involvement in illegal activity by deleting more than 30,000 emails she claimed were personal and not related to her job as top US diplomat. After the FBI announcement Trump appeared exasperated.
