The New York Times first reported that the former New York Democratic congressman would enter the plea Friday in Manhattan.
Former U.S. Rep. Anthony Weiner will appear in federal court to face criminal charges in an investigation of his online communications with a teenage girl in North Carolina. Although, the unnamed victim never meant to press charges as she thought their convos were consensual. Federal sex offenders can't be alone with children, and if Weiner and Abedin do finally get divorced, Weiner cannot seek custody of his son.
Bloomberg News reported Weiner's plea agreement called for a sentence between 21 and 27 months.
An investigation was launched last September into reports that Weiner had been sending sexually explicit messages to a 15-year-old girl in North Carolina, The Times reported.
USA authorities have been investigating reports that Weiner, 52, sent explicit messages past year to a teenage girl in North Carolina.
As part of the FBI investigation, agents seized his laptop computer, which had emails to his then-wife, Huma Abedin, a senior adviser to Clinton's presidential campaign.

In October, just days before the election, FBI director James Comey announced the bureau was reopening its closed investigation into whether ex-Secretary of State Clinton had used a private email server for classified documents in order to assess the newly-discovered correspondence.
She also accused him of asking her to undress on camera.
That inquiry was brief. "Based on our review, we have not changed our conclusions" not to recommend criminal charges against Clinton, Comey wrote.
Mrs Clinton partly blamed her election loss to Republican Donald Trump on Mr Comey's announcement.
Weiner's lawyer, Arlo Devlin Brown, didn't immediately return a message Friday.
Weiner resigned from Congress in 2011 after admitting to a series of online sexual relationships.
He ran for New York City mayor in 2013 and was leading several polls until it was revealed he had continued his questionable behavior. That bid was ruined when news broke that Weiner, using the alias "Carlos Danger", had sent explicit pictures to an IN woman.
