Republican nominee Donald Trump was quick Monday to insult Anthony Weiner, who is set to split with his wife, Hillary Clinton aide Huma Abedin, after the former New York representative was caught up in yet another sexting scandal. But while the blustery billionaire promptly threw stones, he might just live in a (gold-accented) glass penthouse.

Weiner and Abedin were a Democratic power couple, with Bill Clinton even officiating their wedding, but the disgraced politician's sexting scandals in 2011, 2015 and this latest chapter all but derailed the marriage.

"After long painful consideration and work on my marriage, I have made the decision to separate from my husband," Abedin said in statement. "Anthony and I remain devoted to doing what’s best for our son, who is the light of our life. During this difficult time, I ask for respect for our privacy."

Trump pounced on the opportunity to blast Clinton, his Democratic opponent in the race for the White House.

"Huma is making a very wise decision. I know Anthony Weiner well, and she will be far better off without him," he said in a statement. "I only worry for the country in that Hillary Clinton was careless and negligent in allowing Weiner to have such close proximity to highly classified information. Who knows what he learned and who he told? It's just another example of Hillary Clinton's bad judgment. It is possible that our country and its security have been greatly compromised by this."

But while he criticized Weiner, Trump, who is on his third marriage, has seen some times of nuptial tumult. L.A. Times reporter Matt Pearce pointed out that that the book "Trump Nation" detailed how the real estate businessman insulted his crying first wife in public and Trump's forceful deal-brokering over a pre-nuptial agreement with his second wife.

Trump's first marriage with Ivana Trump — the mother of Trump children Eric, Ivanka and Donald Jr. — ended in very public fashion as an affair surfaced with his later-second wife, Marla Maples, mother of Trump daughter Tiffany.

A 1990 Vanity Fair profile of the split laid bare some of the more harsh aspects of Ivana and Donald's relationship, including Trump telling friends, "I would never buy Ivana any decent jewels or pictures. Why give her negotiable assets?" Ivana became a heroine as the story played out in the tabloids.

"When a man leaves a woman, especially when it was perceived that he has left for a piece of ass — a good one! — there are 50 percent of the population who will love the woman who was left,” he told Vanity Fair.

It was an ugly end to a 15-year marriage, but it has changed with time and Trump and Ivana have returned to an amicable relationship. They even talk about the campaign, with Ivana telling Us Magazine in April, "We speak before and after the appearances and he asks me what I thought."
