Hillary Clinton received a set of written questions Tuesday, to be answered under oath, about the reasons she set up her private server system and why she scrubbed emails from it ahead of an FBI investigation.

The 25 inquiries came in a Freedom of Information Act lawsuit filed by conservative-leaning Judicial Watch, and each pressed Clinton on inconsistencies in her past statements or questions left unanswered by depositions taken in the case so far.

For example, Clinton was asked about the circumstances surrounding the deletion of thousands of work-related communications, her contact with technology aide Bryan Pagliano and her testimony last year before the House Select Committee on Benghazi.

Judicial Watch attorneys pressed the former secretary of state on the reasons behind her decision to set up a private email network other than "convenience," which was her original justification for the server.

However, the FBI has since explained that Clinton used multiple devices and servers to access her emails.

Clinton has 30 days to return written answers to the questionnaire. Her responses will be considered sworn testimony by the court, which stopped short of granting Judicial Watch's request for a deposition when ordering Clinton to address the questions.
