One of Hillary Clinton's closest advisers, Huma Abedin, is becoming increasingly entangled in the scandal surrounding Clinton's exclusive use of a private email server while at the State Department.

Back in July, it was reported that David McCullough, the inspector general for the intelligence community, had found nearly a dozen instances that classified information had been communicated using Clinton's private server. Earlier this week, it was announced that at least two “top secret” documents were present on Clinton's server.

Then, on Monday, it was revealed in federal court that Abedin also used an account on Clinton's email server for matters related to her position at the State Department — a very unusual occurrence for any federal employee. Soon after learning about the presence of sensitive documents, according to Politico, Abedin retained a lawyer, in anticipation that she will soon face more scrutiny from congressional investigators.

The seriousness of such secret information being present on Clinton's server, according to Politico:

“Abedin had been granted “special government employee” status, allowing her to work both for Clinton and the private sector — and it’s unclear if she continued using the server that appears to have held classified information following her departure from her full-time State gig...”

The Senate Judiciary Committee, headed by Senator Chuck Grassley (R-IA), has taken a particularly keen interest in Abedin, and her role in the scandal.

According to the Committee, Abedin is being investigated by the State Department's inspector general for misconduct, although Adedin's lawyers told Politico that they know of no investigation.

The Clinton email fiasco took a new turn on July 31st when a federal judge ordered Clinton, along with Abedin and Clinton's former Chief of Staff, Cheryl Mills, to certify under penalty of perjury that they would not further destroy any evidence in relation to the investigation.

The trio was given one week to certify themselves. Clinton, however, was the only one of the group to do so.
