FBI has a search warrant to review emails

A law enforcement official says the FBI has obtained a search warrant to start reviewing newly discovered emails that may be tied to the Hillary Clinton email investigation.

Both the Hillary Clinton and Donald Trump campaigns made the rounds on Sunday, reacting to the FBI's announcement that it found more information that may effect its previous investigation into Clinton's private email server and that director Comey may not have seen the emails before making the announcement.

"Why would you release information that is so incomplete when you haven't even seen the material yourself, 11 days before an election? Why would you talk about an ongoing investigation? I just have no way of understanding these actions. They're completely unprecedented," said Democratic Vice Presidential nominee Tim Kaine.

Republican Vice Presidential candidate Mike Pence said, "Look, this is clearly a very serious matter and we respect the institution of the FBI and are confident that they'll handle this in a professional and a timely way."

The emails were discovered as part of an investigation into Anthony Weiner's sexting scandal on devices taken from top-Clinton aide Huma Abedin.

Clinton's campaign is questioning whether the FBI and Justice Department have the proper warrants to look at the emails and suggesting that anything they found belonged to Huma and are likely duplicates of ones she already shared with the FBI months ago.

"The Justice Department may not have a warrant to look at these messages. So we just want all the information out there," said Clinton campaign manager Robby Mook.

But Republicans are doubling down and casting doubt on those assertions.

"This has to be a substantial development. I just don't see Director Comey opening this case back up 11 days before the election unless it is quite serious," said California Rep. Devin Nunes.

With early voting already started across the country, both campaigns continue to fight hard as polls show the race tightening.
