Hillary Clinton called on the FBI to immediately release the "full and complete facts" regarding the bureau's review of additional emails related to the investigation into her private server.
"We don't know the facts which is why we are calling on the FBI to release all of the information that it has," Clinton told reporters at a press conference.
FBI Director James Comey announced in a letter to the Senate Judiciary Committee on Friday that FBI investigators would review additional emails related to the investigation into Clinton's private email server.
Clinton said her campaign was not given any notice about the letter and has no additional information.
Multiple federal officials told NBC News the emails were discovered as part of a separate investigation into former Democratic Rep. Anthony Weiner, who is separated from top Clinton adviser Huma Abedin.
"We don't know what to believe and I'm sure there will be even more rumors," Clinton said when said when asked about the reported link to Weiner.
Comey in July announced the FBI would recommend no criminal charges against Clinton for her use of a private email server while secretary of state.
