Other news sources reported the extradition (curiously none of the mainstream US news sites did), but Fox has connected the dots. This one should be fun to watch. Why else bring this guy to the US?
Source: No 'coincidence' Romanian hacker Guccifer extradited amid Clinton probe | Fox News
The extradition of Romanian hacker “Guccifer” to the U.S. at a critical point in the FBI’s criminal investigation of Hillary Clinton’s email use is “not a coincidence,” according to an intelligence source close to the case.
One of the notches on Guccifer’s cyber-crime belt was allegedly accessing the email account of Clinton confidant Sidney Blumenthal, one of Clinton’s most prolific advice-givers when she was secretary of state. It was through that hack that Clinton's use of a personal account -- clintonemail.com -- first came to light.
