The 2016 Democratic front-runner on Monday told a federal judge that Abedin — long considered her boss’s keeper and even dubbed her “shadow” — had her own email account on Clinton’s now infamous home-brewed server, “which was used at times for government business,” Clinton acknowledged. That’s an unusual arrangement, even for top brass at the State Department.

Abedin has hired a team of lawyers, one of whom is a former Clinton aide, who are responding to information requests from the courts and State. They’ve denied any wrongdoing on the part of their client and said Abedin is cooperating with requests for official emails in her possession, aiming to turn over all her correspondence by the end of August…

Steven Aftergood, who directs the Federation of American Scientists’ project on government secrecy, said Abedin’s potential access to secret materials could be a problem.

“What happens if [a former government employee] still retains access through a prior server, to information that was justified by a previous position? That’s not supposed to happen — and that’s one of the anomalies that are created by the private server,” Aftergood said.
