Hillary Clinton met Saturday morning with the FBI regarding the agency’s investigation into her use of a private email server for official correspondence while secretary of state.

The voluntary meeting lasted about three-and-a-half hours and was conducted at FBI headquarters in Washington, D.C., according to the Clinton campaign.

Clinton “is pleased to have had the opportunity to assist the Department of Justice in bringing this review to a conclusion” campaign spokesman Nick Merrill said in a statement. He also said Clinton, the presumptive Democratic presidential nominee, would have no further comment about the interview.

The campaign issued the statement Saturday shortly before 12:30 p.m. ET, practically minutes after Clinton returned to her Washington home, then departed again about 30 minutes later.
