There’s a single block on Manhattan’s Upper East Side that perfectly embodies the conflicted state of relations between the Trump family and Russia.

The block is East 64th Street in Manhattan between Madison and Fifth avenues, one of the poshest in the city.

Residents and owners have over the years included Trump’s children, the family of Jared Kushner, a Russian oligarch, a Soviet-born billionaire and major GOP donor, and the family of another Russian oligarch friendly with Ivanka.

The story of East 64th Street isn’t a story of collusion over a cup of borrowed sugar, but rather a story about the global elite — people from all over the world who are connected by networks of money, power and influence that concentrate themselves in cities like New York and London.

Just across the street from Central Park, you’ll find the limestone mansion that Trump’s children once called home. Don Junior, Ivanka and Eric Trump moved into 10 E. 64th Street after their mother, Ivana, was granted sole custody in her tumultuous 1992 divorce. Ivana still lives in the building.

Across the street, at 11 E. 64 Street, sits a mansion owned by Oleg Deripaska, the Russian oligarch and aluminum tycoon who has been sanctioned by the U.S. government.

Deripaska’s stake in the building was revealed in a case brought in New York by Alexander Gliklad, who was seeking billions in dollars from Deripaska:

U.S. government sanctions prevent Deripaska from selling the pied-a-terre he purchased a decade ago for $42.5 million from art dealer Alec Wildenstein.

Complicating matters, Deripaska’s house was occupied last year by the ex-wife and children of Roman Abramovich, another Russian oligarch connected to Putin who is perhaps best known for his ownership of London’s Chelsea Football Club.

Dasha Zhukova, Abramovich’s ex-wife, listed her address as 11 East 64th Street on this New York City property record a year ago:

Perhaps not coincidentally, Dasha Zhukova happens to be good friends with Ivanka Trump. The two women have known each other for more than a decade and were photographed together at the U.S. Open tennis tournament during the 2016 presidential election. Abramovich and Kusher have met three to four times in social settings, Bloomberg reported.

Another owner on East 64th Street is Ukrainian-born Len Blavatnick, one of the richest men in the world. Blavatnik spent $90 million to buy a Gilded Age limestone townhouse at 19 E. 64th St.

Blavatnik is a business partner of his 64th Street neighbor, Oleg Deripaska. The two have stakes in Rusal, one of the world’s biggest aluminum producers, although Deripaska was recently forced by the U.S. government to give up control of the company.

One of Rusal’s major shareholders, SUAL Partners Limited, was founded by Blavatnik and the sanctioned Russian oligarch Viktor Vekselberg. Blavatnik resigned from Rusal’s board two days after Donald Trump was elected president.

Blavatnik, who is now a citizen of both Britain and America, donated $1 million donation to Trump’s inauguration

During the 2016 election, Blavatnik contributed another $6.35 million to leading Republican candidates and incumbent senators.

The top recipient was Senate Majority Leader Mitch McConnell, who raked in $2.5 million for his GOP Senate Leadership Fund under the names of two of Blavatnik’s holding companies, Access Industries and AI Altep Holdings.

Marco Rubio’s Conservative Solutions PAC and his Florida First Project received $1.5 million through Blavatnik’s two holding companies. Lindsey Graham of South Carolina received $800,000 from Blavatnik’s company. Ohio Governor John Kasich took $250,000 from Blavatnik and Arizona Senator John McCain another $200,000.

Blavatnik had tried to buy 19 E. 64th St. for years. He even sued the previous owners, the Wildenstein family, when an earlier deal fell through. His lawsuit describes the building in almost loving terms:

The Kushners long had a presence on the block as well. A family company purchased 26 E. 64th Street in 1989 and sold it 2007, the same year that Jared met Ivanka.

Finally, the last person I could find connected to Trump on this fascinating block was Verina Hixon, who used to rent an apartment at 14 E. 64th Street. She was kicked out for nonpayment of maintenance fees.

Hixon’s story is just as wild as any of her better-known neighbors. The Daily Beast ran a story about her titled “The Party Girl Who Brought Trump to His Knees.”

In 1982, the Austrian-born, Swiss-educated Hixon bought four apartments in Trump Tower for $10 million. The apartments were widely believed to belong to Hixon’s “friend,” John Cody, head of a local Teamsters union that was closely linked to the Cosa Nostra. Cody went to jail, Hixon went bankrupt and lost the Trump Tower apartments.

She found a new home on East 64th Street where she befriended Ivana Trump. Ivana visited Hixon’s $20 million chalet in St. Moritz, Switzerland. Ivana brought along her dachshunds who relieved themselves all over Hixon’s home and that was the end of their friendship.
