A long-awaited State Department inspector general report on the impact of personal email use on recordkeeping at State is expected to be made public any day. And as many Americans prepare for the traditional Memorial Day kickoff to the summer season, longtime Clinton aide Cheryl Mills is scheduled to sit for a sworn deposition Friday in a Freedom of Information Act lawsuit brought by the conservative group Judicial Watch.

Mills’ testimony would be the first known time a member of Clinton’s inner circle has been questioned under oath in the email controversy. Another top Clinton aide, Huma Abedin, is set to testify next month. And Clinton herself is awaiting a judge’s ruling on whether she should be required to give a deposition.

No matter how that comes out, Clinton also faces an ongoing FBI investigation into the email set up. Some of her aides have already been questioned. She’s expressed a willingness to sit down with investigators — something they’re expected to take her up on in the next few weeks. Unless it takes place in complete secrecy, such a session would be the highest-profile legal spectacle the former first lady has faced since she testified 20 years ago before a federal grand jury investigating the disappearance and reappearance of Whitewater billing records.
