Former Secretary of State Hillary Clinton has agreed to hand over to the FBI the private email server that she used on duty.
Hillary Clinton’s use of private email has generated a barrage of criticism as she runs for president.
Critics say that her set-up was unsecure, contrary to government policy and designed to shield her communications from oversight.
The FBI is investigating whether classified information was improperly sent via the server and stored there.
Hillary Clinton initially handed over thousands of pages of emails to the state department, but not the server.
Hillary Clinton’s use of private email has been a major issue in the presidential race. Polls show an increasing number of voters view her as “untrustworthy” due in part to the questions surrounding her email use.
Under US federal law, officials’ correspondence is considered to be US government property.
Government employees are encouraged to use government email accounts although some top officials have used personal accounts in the past.
In March, Hillary Clinton said she and her lawyers made the decision over what would be considered work-related email when the state department asked for records from former secretaries of state.
The emails deemed work-related were about half of the 60,000 emails she sent in total during her time in office. The emails she deemed personal were deleted, Hillary Clinton said.
Since then, the state department has been releasing the emails to the public in batches about once a month.
On August 11, the state department said it would not be releasing a portion of Hillary Clinton’s emails because some of the messages were retroactively determined to be “top secret”.
