Former Congressman and New York City mayoral candidate Anthony Weiner sent explicit photos to a woman multiple times over the past 19 months, according to a New York Post report published late Sunday.

The report said Weiner, who is married to Hillary Clinton's top aide, Huma Abedin, described his sexual fantasies and masturbation in messages to the unidentified woman and called her "literally a fantasy chick."

One of the photos Weiner sent the woman showed his underwear-clad crotch as his son Jordan slept next to him in bed.

When contacted by the Post, Weiner admitted he and the woman "have been friends for some time," but added that their conversations were "private ... and were always appropriate."

Weiner, 51, added that he had never met the woman in person, despite repeatedly inviting her to visit him in New York.

By Monday morning, Weiner's Twitter account appeared to have been taken down.

Weiner spent 12 years in the House of Representatives before resigning in June 2011 after posting an explicit image of himself on his Twitter account. At the time, he admitted that he had "exchanged messages and photos of an explicit nature with about six women" over the previous three years.

With Abedin's public support, Weiner entered the New York City mayoral race in 2013. However, his campaign collapsed when a second woman, Sydney Leathers, came forward to claim Weiner had sent her more explicit photos while using the alias "Carlos Danger." Weiner finished fifth in the Democratic primary with just five percent of the vote.

Weiner's latest correspondent, who described herself to the Post as a supporter of Republican presidential nominee Donald Trump and the National Rifle Association, has two adult children and lives with a boyfriend who routinely travels for work.

The Post reported Sunday that Weiner was concerned that he had repeated his 2011 mistake and posted the photo of his son publicly.

"You do realize you can see you [sic] Weiner in that pic??" the woman messaged.

"Ooooooh ... I was scared. For half a second I thought I posted something," Weiner responded. "Stop looking at my crotch."

"Whatever. You did it on purpose," she replied, adding, "O [sic] I see you thought you posted on your TL [public timeline] not DM [direct messages]. S–t happens be careful."
