Official: FBI knew for weeks about newly discovered emails

FBI investigators in the Anthony Weiner sexting probe knew for weeks about the existence of newly discovered emails potentially related to the investigation of Hillary Clinton's private email server, a law enforcement official said on Sunday.

In his letter that roiled the White House race, FBI Director James Comey said he was briefed last Thursday about that development. He told Congress on Friday that the bureau had found emails in an unrelated case that might be relevant to the Clinton inquiry.

The emails were found on a device that belonged to Weiner, the estranged husband of close Clinton aide Huma Abedin.
