Former Democratic congressman Anthony Weiner is cooperating with authorities in the FBI investigation of his laptop that contains emails that prompted the Federal Bureau of Investigation to reopen its probe into Hillary Clinton's use of an unauthorized email server.
The news that Weiner is cooperating, reported by Fox News' Bret Baier on Sunday, would help law enforcement with the investigation, since officials didn't yet have a warrant to read through the material found on the device.
Though FBI Director James Comey told lawmakers Friday his agency found emails related to Hillary Clinton's private email server, he didn't yet have a warrant to read them.
As of Saturday night, the FBI had not received a search warrant from the Justice Department, an unnamed agency official told Yahoo News, but the agency was in talks to get one. When Comey wrote the letter, "he had no idea what was in the content of the emails," said one official.
Neither the Justice Department nor the FBI immediately returned a request for comment.
Comey has begun participating in briefings with the Republican chairman and Democratic ranking members of congressional committees, according to Bill House, a congressional correspondent for Bloomberg News, citing unnamed sources.
Comey wrote a letter to eight lawmakers Friday to inform them that he was reopening the FBI case into Clinton's unauthorized email server after the agency found emails in a laptop obtained from Weiner as part of a separate investigation into a sexting scandal. Weiner reportedly shared the laptop with his estranged wife Huma Abedin, a top Clinton aide.
Abedin claimed ignorance on how at least 10,000 emails of interest to the FBI's investigation ended up on the laptop, the Washington Post reported. Her lawyers also did not search the computer for work-related material over the summer when she agreed to provide emails to the State Department.
Late Sunday morning, news broke that the Justice Department and the FBI were taking part in discussions with Abedin's lawyers to conduct a full search of the new emails, according to CNN.
In his letter, Comey admitted he did not yet have the authority to assess the emails, but said the material "may be significant."
Reports came out Saturday that Attorney General Loretta Lynch's department disapproved of Comey's decision to inform the lawmakers, as it deviated from agency policy not to comment on ongoing investigations.
Officials told CNN that the Justice Department could do little to stop Comey after the controversy that resulted from Lynch's private meeting with former President Bill Clinton during the summer.
Comey has been hit by backlash for sending the letter to lawmakers just under two weeks before the Nov. 8 election. Democrats in particular have lashed out, adopting Republican nominee Donald Trump's refrain that the election is "rigged."
The Clinton campaign, including the candidate herself, has called on the FBI to release all "relevant facts" they have on the emails.
In an internal memo obtained by Fox News on Friday, Comey explained to staffers he chose to break with normal procedure because he felt "an obligation" to tell Congress because he recently testified that the investigation had ended and that he recommended no charges be brought against the former secretary of state.
