Hillary Clinton gave a voluntary interview to the FBI Saturday morning as part of the investigation into her use of a private email server for official emails while serving as secretary of state, a campaign aide confirmed.
"She 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. "Out of respect for the investigative process, she will not comment further on her interview."
The long-awaited interview on whether Clinton mishandled classifed information submitted on her private email system took place at the FBI headquarters in Washington, D.C., and lasted approximately three and half hours, a source told NBC News.

Though the interview was not unexpected, it came as Attorney General Loretta Lynch faces criticism that the investigation is politically tainted after an encounter with former president Bill Clinton earlier this week on a tarmac at Phoenix's Sky Harbor International Airport.
Speaking at a summit in Aspen, Colorado, Friday, Lynch acknowledged the impromtu meeting with Bill Clinton "casts a shadow" over the public perception of the neutrality of the investigation. But, Lynch added, she will fully accept the recommendations of career prosecutors, investigators and FBI Director James Comey on whether to bring criminal charges in the investigation.
"This case will be resolved by the team that has been working on it from the beginning,'' Lynch said.
