The Democratic presidential candidate’s closest aide Huma Abedin is finally leaving her scandal-prone ex-​US ​congressman Anthony Weiner after his latest sexing scandal.

The top aide announced the news on Monday after the New York Post shared explosive pictures of her husband’s latest sexting shocker.

While the scandal does not directly relate to Mrs Clinton, Republican nominee Donald Trump used the news to criticise her judgment.

“I only worry for the country in that Hillary Clinton was careless and negligent in allowing Weiner to have such proximity to highly classified information,” he said.

In a statement, Ms Abedin said: “After long and painful consideration and work on my marriage, I have made the decision to separate from my husband.

“Anthony and I remain devoted to doing what is best for our son, who is the light of our life. During this difficult time, I ask for respect for our privacy.”

As Abedin travelled the country campaigning for Clinton, the disgraced mayoral wannabe sexted a brunette — and even sent her a lurid crotch shot with his toddler son in the picture.

Weiner deleted his Twitter account early on Monday morning after the news broke.

The stay-at-home cad shot the revealing photo while discussing massage parlours “near my old apartment” shortly after 3am on July 31, 2015, a screenshot of the exchange shows.

Weiner was clearly aroused by his conversation with the 40-something divorcee when he abruptly changed the subject.

“Someone just climbed into my bed,” Weiner wrote.

“Really?” she responded.

Weiner then hit “Send” on the cringe-inducing image, which shows a bulge in his white, Jockey-brand boxer briefs and his son cuddled up to his left, wrapped in a light-green blanket.

“You do realise you can see you[r] Weiner in that pic??” the woman wrote.

Moments after forwarding the photo, Weiner freaked out over the possibility he had accidentally posted it publicly — just as he did during the infamous episode that forced him to resign from Congress in 2011.

“Ooooooh ... I was scared. For half a second I thought I posted something. Stop looking at my crotch,” Weiner wrote back.

“Whatever. You did it on purpose,” she replied.

“O I see you thought you posted on your TL [public timeline] not DM [direct message]. S — t happens be careful,” she added.

The object of Wiener’s affections is his polar opposite politically: a self-avowed supporter of Donald Trump and the National Rifle Association who’s used Twitter to bash both President Obama and Clinton.

Screenshots show the electronic chats began in late January 2015 and continued through earlier this month, according to the woman, who spoke to The Post on condition of anonymity.

And while Weiner repeatedly invited her to visit him in New York City, she said, “We never met.”

Asked for comment, Weiner admitted he and the woman “have been friends for some time.”

“She has asked me not to comment except to say that our conversations were private, often included pictures of her nieces and nephews and my son and were always appropriate,” he said.

But the picture featuring his son was one of more than a dozen selfies sent to the woman by Weiner, 51 — and most show him posing shirtless to flaunt his well-toned physique.

One is even a near-replica of the crotch shot that first turned him into a national laughing-stock — except he was wearing white boxer briefs instead of grey ones.

Weiner wrote, “My mood ...” before sending the overtly sexual photo on June 14, 2015, prompting the woman to respond, “O goodness.”

Many of Wiener’s messages show him bragging about his manhood and shamelessly lusting after the woman.

The latest online dalliance developed when Weiner began exchanging direct messages with her via Twitter following an online clash with a second woman, according to the gal.

As their conversation progressed, she mentioned having “over 30 nieces and nephews,” at which point Weiner responded by asking: “Wow. Got your own? (Weiner sees opening to ask about [your] status).”

When she tried to end the conversation by saying “it’s time for bed,” Weiner wrote back: “Sleeping alone? Asking for a friend?” before adding, “That was a fib.”

Weiner frequently steered the conversation toward sex, as many of their discussions initially involved such mundane topics as their respective workout regimens.

“I am always, uh, raging after the gym,” he wrote in one of several apparent references to his genitalia.

Another time, he wrote about how “Id [sic] put someone’s eye out with this thing. #Overdue.”

When the woman sent Weiner a selfie that showed her in a cleavage-baring, red lace dress, Wiener’s response was “Holy f — kits f- -k,” while another shot of her standing next to a woman at the same event prompted him to write: “Conjured some high school fantasies.”

At one point, she sent him a shot of herself wearing a pair of black tights with a rip in the rear, near the midlife, along with the message, “Buns of steel.”

“I’ll need a bigger hole,” Weiner responded, adding a smiling emoji with its tongue sticking out.

The sext fiend also admitted to fantasising about her, saying “guess who visited me in a dream last night/this morning ... uh, you. obv.”

In another message, he blamed her for keeping him awake the previous night. “I did not sleep well ... Horny as f — k,” he wrote.

When she suggested it was a “disease,” he wrote back: “You are a carrier.”

He even confessed to masturbating while thinking about her, calling her “literally a fantasy chick.”

“And I mean literally. So now you know how I got to sleep last night,” he wrote, adding a purple demon emoji.

After she sent him a cartoon image of a pump bottle of hand lotion and a box of tissues, he responded with a graphic, homemade text-and-emoji image of an ejaculating penis.

“OK…..Enough of that! she wrote.

“Yeah. I taxed myself too much on that one. So anyway, what are you wearing,” he wrote back, adding a winking, tongue-out emoji.

Following his first sexting scandal, Weiner claimed to have undergone therapy, having sat down with Abedin for a 2012 People magazine interview in which he said he was happy as a stay-at-home dad. “The only next dramatic steps I’m planning on are Jordan’s first,” he said, in reference to their then-6-month-old son.

His purported rehabilitation led to an improbable lead in the polls for New York mayor in 2013 — until his candidacy collapsed amid revelations that he continued sexting behind the “Carlos Danger” pseudonym.

The latest object of Wiener’s sexting obsession is a woman with two grown children who lives with a boyfriend. She told Weiner that her significant other travelled for work and was only “in town about 10 days a month.”

At one point in their conversation, Weiner offered to take the object of his lust to one of the restaurants co-owned by his younger brother, Jason.

“Lets get together. I’m a big wheel in this town,” Weiner wrote.

Two leading divorce experts told the New York Post Weiner’s latest sexting stunt is grounds for a city child welfare probe.

“I believe ACS will start investigating now,” said lawyer Raoul Felder, referring to the Administration for Children’s Services. “He’s doing these things on camera and he brings his child into bed with him.”

Leading family law expert Michael Stutman, of the law firm Stutman Advocate Stutman & Lichtenstein, agreed that Weiner is a prime candidate for an ACS investigation because of “the child’s involvement in what appears to be very perverted behaviour.”
