Huma Abedin has been Hillary Clinton’s top aide and assistant for years.

But now, Senator Chuck Grassley (R-Iowa), head of the Senate Judiciary Committee, is now digging into why Abedin was allowed to retain special government employee status while also working for a consulting firm. This is an ongoing effort by Grassley to get some answers from both Hillary Clinton and Huma Abedin, as both used private email accounts while working for the State Department.
