Hilary Clinton's emails were centre stage in her failed presidential bid.
Now correspondence from an ex-Clinton aide has been released by the US State Department.
During the campaign, WikiLeaks published Democratic Party e-mails that American intelligence agencies say were hacked by Russia.
This time, a Freedom of Information Act by conservative watchdog group Judicial Watch has resulted in a batch of emails from former Clinton aide Huma Abedin being released.
They were found on the laptop of her estranged husband, ex-Congressman Anthony Weiner, as the FBI investigated the 'sexting' scandal surrounding him.
No startling revelations have emerged from Abedin's emails. Some concern Clinton's daily schedules. Others are marked classified and have been heavily redacted.
Examination of Weiner's computer led then FBI boss James Comey to announce shortly before the 2016 election that he was reopening his probe into Clinton’s use of a private email server for official correspondence when she was Secretary of State under former President Barack Obama.
Clinton has said that announcement contributed to her defeat.
