| 1 | Hillary Clinton has agreed to hand over to the FBI the private email server that she used as secretary of state. |
| 2 | Her use of private email has generated a barrage of criticism as Mrs Clinton runs for president. |
| 3 | Critics say that her set-up was unsecure, contrary to government policy and designed to shield her communications from oversight. |
| 4 | The FBI is investigating whether classified information was improperly sent via the server and stored there. |
| 5 | Mrs Clinton initially handed over thousands of pages of emails to the state department, but not the server. |
| 6 | Her lawyers will also hand over to the FBI memory sticks which contain the copies of the emails. |
| 7 | Her use of private email has been a major issue in the presidential race. |
| 8 | Polls show an increasing number of voters view her as "untrustworthy" due in part to the questions surrounding her email use. |
| 9 | Under US federal law, officials' correspondence is considered to be US government property. |
| 10 | Government employees are encouraged to use government email accounts although some top officials have used personal accounts in the past. |
| 11 | In March, Mrs 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. |
| 12 | The emails deemed work-related were about half of the 60,000 emails she sent in total during her time in office. |
| 13 | The emails she deemed personal were deleted, Mrs Clinton said. |
| 14 | Since then, the state department has been releasing the emails to the public in batches about once a month. |
| 15 | However on Tuesday, the state department said it would not be releasing a portion of the emails because some of the messages were retroactively determined to be "top secret". |
| 16 | Senior Republican Reince Priebus said Mrs Clinton had "run out of options" in the face of FBI scrutiny. |
