"It's pretty strange to put something like that out with such little information right before an election," Clinton, the Democratic presidential nominee, said with a nod during a rally in Daytona Beach, Fla.


"In fact, it's not just strange, it's unprecedented and it is deeply troubling," she added.

"When you do this 11 days before a presidential election and you don’t provide many details, but details are apparently being given by the FBI to the press, this is very, very troubling, and we hope that the director — and we really think that he should give a clearer accounting of exactly what’s going on right now," Kaine told Vice News.

Clinton has challenged the FBI to release information relating to the new emails that Comey said were discovered during a separate investigation but that may be pertinent to the probe into Clinton's use of a private email server while secretary of State.

Comey sent a letter to lawmakers on Friday announcing the existence of the new emails. The New York Times reported the emails were discovered during an investigation into former Rep. Anthony Weiner (D-N.Y.), the estranged husband of top Clinton aide Huma Abedin.

Democrats have trained their fire on Comey and ramped up pressure for the FBI director to release more information about the new emails.

A government official told The Hill on Saturday that the Justice Department's stance regarding the new emails was to abstain from taking any actions that could impact the election.
