Hillary Clinton demanded Friday during a last-minute press conference that FBI Director James Comey tell the public more about the FBI's newest probe into the use of her email server, arguing that people deserved to get "the full and complete facts" just 10 days before the presidential election.

Comey sent a letter to Congressional committee leaders yesterday informing them that an FBI investigation into former New York Congressman Anthony Weiner led the agency to discover more emails connected to Clinton's email account.

"The American people deserve to get the full and complete facts. The director himself has said that he doesn't know whether the emails… are significant or not," Clinton said Friday evening. "It's imperative that the Bureau explains this issue in question, whatever it is, without delay."

"Right now, your guess is as good as mine. And I don't think that's good enough [...] If they're going to be sending this kind of letter… then they need to share whatever facts they claim to have with the American people."

Clinton added that she believed the issue wouldn't significantly impact the election, saying that voters have "made up their minds" about the issue.

"People, a long time ago, made up their minds about the emails. I think that's factored in… and now they're choosing a president," she said.

In Comey's letter to congressional leaders, he acknowledged that the agency still had to "assess their importance to our investigation."

In a tweet published Saturday, Trump campaign manager Kellyanne Conway called the Clinton camp's response to the probe an "all-out assault on Comey by Team Clinton," describing it as "dangerous & unfair."
