FBI obtains warrant to examine Clinton e-mails

This comes as a prominent Democrat accused FBI Director James Comey of breaking the law by trying to influence the election.

The warrant will allow the Federal Bureau of Investigation to examine the emails to see if they are relevant to its probe of the private email server used for government work by Clinton, the Democratic presidential nominee, while she was secretary of state from 2009 to 2013.

FBI officials were unavailable for comment on the status of their investigation. Reuters could not independently confirm that the search warrant had been issued.

Comey came under heavy pressure from Democrats on Sunday to quickly provide details of the emails, as Clinton allies worried the prolonged controversy could extend beyond the Nov. 8 election and cast a shadow over a Clinton transition if she wins the White House.

Comey's disclosure of the email discovery in a letter to Congress on Friday plunged the final days of the White House race between Clinton and Republican Donald Trump into turmoil. Clinton had opened a recent lead over Trump in national polls, but it had been narrowing even before the email controversy resurfaced.

U.S. Senate Democratic leader Harry Reid sent a letter to Comey on Sunday suggesting he violated the Hatch Act, which bars the use of a federal government position to influence an election.

"Through your partisan actions, you may have broken the law," Reid, a senator from Nevada, said in the letter to Comey.

Clinton campaign chairman John Podesta and campaign manager Robby Mook questioned Comey's decision to send a letter notifying Congress of the email review before he even knew whether they were significant or relevant.

Comey's letter was "long on innuendo, short on facts," Podesta said on CNN's "State of the Union" program, and accused the FBI chief of breaking precedent by disclosing aspects of an investigation so close to the election.

"We are calling on Mr. Comey to come forward and explain what's at issue here," Podesta said, adding the significance of the emails was unclear.

"He might have taken the first step of actually having looked at them before he did this in the middle of a presidential campaign, so close to the voting," Podesta said.

Comey's letter was sent over the objections of Justice Department officials. But those officials did not try to stop the FBI from getting the warrant, a source familiar with the decision said, because they are interested in the FBI moving quickly on the probe.

Sources close to the investigation have said the latest emails were discovered as part of a separate probe of former Democratic U.S. Representative Anthony Weiner, the estranged husband of Clinton aide Huma Abedin.

Weiner is the target of an FBI investigation into illicit text messages he is alleged to have sent to a 15-year-old girl in North Carolina. The FBI already had a warrant to search Weiner's laptop in that probe, but needed a warrant to look at the material that might be related to Clinton.
