Republican presidential hopeful Donald Trump, who has mostly been targeting his political rivals thus far, opened a new line of attack on Friday by slamming Hillary Clinton’s Indian-American aide Huma Abedin in the wake of the Democratic front-runner’s escalating private email server controversy.At a rally in Massachusetts, Trump charged that Abedin, who served as Deputy Chief of Staff while Clinton was Secretary of State, used to receive classified information which she then shared with her “sleazebag” husband, former Democratic lawmaker Anthony Weiner. Abedin is currently Vice Chairman of Clinton’s presidential campaign.
