Huma Abedin, a top aide to Clinton and her former deputy chief of staff, is married to Anthony Weiner, a former Congressperson who has been beset by two “sexting” scandals, in which it was publicly revealed he sent sexual text messages to other women. On August 28, 2016, the New York Post reported that Weiner had been caught in his third sexting scandal. The next day, Abedin announced she is separating from him and divorcing him.

On September 21, 2016, the Daily Mail further revealed that the still unnamed woman he’d been sexting with in recent months in fact was only 15 years old. (The Daily Mail, 9/21/2016)
This raised the possibility that Weiner could face serious federal criminal charges, especially if the girl lives in a different state, which it turns out she does. (Rolling Stone, 9/22/2016)
As a result, after the Daily Mail article, top federal prosecutors in New York (where Weiner lives) and North Carolina (where the unnamed girl lives) fought over who would get to prosecute the case. The Justice Department gave the case to Preet Bharara, a US attorney in New York.
The New York Times will later report that also in late September 2016, “agents in the FBI’s New York field office understood that the Weiner investigation could possibly turn up additional emails related to Mrs. Clinton’s private server, according to a senior federal law enforcement official.”
Then, on October 3, 2016, the FBI seizes several electronic devices owned by Weiner, including a computer laptop, his iPhone, and his iPad. Several days later, FBI agents also confiscate a Wi-Fi router that could identify any other devices that he had used. This is also according to an unnamed US law enforcement official.
When FBI agents search the seized devices, they find thousands of emails sent to or from Abedin on the laptop, because apparently it was used by both Abedin and Weiner before they separated. According to unnamed “senior law enforcement officials,” some of the emails are sent between Abedin and other Clinton aides. However, only FBI agents and Justice Department prosecutors directly involved in the Weiner investigation can look at the evidence, and those who took part in the Clinton email investigation, closed in July 2016, do not have the legal authority, at least not yet.
FBI Director James Comey will learn about the emails in mid-October 2016. He will be brief October 27, 2016, and he will write a letter to Congress the next day announcing that he is reopening the Clinton email investigation at least long enough to determine the possible relevance of the emails to the Clinton case.
