Dan Goldstein is a Brooklyn attorney who reportedly yelled at Ivanka Trump on a JetBlue flight from New York to Palm Beach on December 22. He ended up getting kicked off the flight, which was delayed because of his behavior. His husband, Matthew Lasner, tweeted about the incident, but later deleted his messages and then his entire Twitter page.

JetBlue issued a statement, confirming that passengers were removed from the flight and given another flight to reach their destination. ABC News reports that the flight was delayed.

Here’s what we know so far about the incident and a look at Goldstein’s career.

1. Passenger on the Plane Disputes Report That Goldstein Yelled at Ivanka

Ivanka was traveling to Florida with her three children and husband Jared Kushner on a commercial flight and sat in coach with the other passengers. TMZ reports that Goldstein yelled at her, “Your father is ruining this country.”

Goldstein, who was carrying his son, then yelled, “Why is she on our flight. She should be flying private.”

JetBlue flight attendants overheard the incident and removed Goldstein, Lasner and their son from the flight. “You’re kicking me off for expressing my opinion?” Goldstein yelled, according to a passenger who spoke with TMZ.

As for Ivanka, she ignored Goldstein and kept her children busy with crayons.

Marc Scheff, who sat in front of Ivanka on the plane, told a different story to BuzzFeed News and also shared his version of events on Facebook.

Scheff wrote:

He didn’t accost her directly.

When he got on and saw her, sitting behind me, he said “oh my god. This is a nightmare” and was visibly shaking. He said “they ruin the country now they ruin our flight!” (Context: Boarding and therefore the flight was delayed because they needed to get on first through some other way)

He did not yell. He was also not what I would describe as calm. Agitated maybe. His husband behind him was very calm. His son is adorable and sharply dressed.

When the JetBlue staff went back to speak to the man I overheard Ivanka say to them “I don’t want to make this a thing.” My assessment is that she was happy to let the man take his seat. She handled the situation calmly and with class. Security made the call to remove the man.

And for good reason. The man’s calm husband had tweeted earlier that his husband was “chasing them down to harass them.”

I did not witness his actual removal some rows back. If he screamed, I didn’t hear it.

2. Lasner’s Husband Tweeted That Goldstein Chased Ivanka & Kushner After Spotting Them at the Airport

An hour before the flight was supposed to take off, Lasner tweeted that Goldstein was “chasing” Ivanka and Kushener “down to harass them,” adding “#banalityofevil.”

However, in his next tweet, Lasner changed his story. “My husband expressed displeasure in a calm tone, JetBlue staff overheard, and they kicked us off the plane,” Lasner wrote.

Lasner also posted a photo of Ivanka on the plane. “Ivanka just before @JetBlue kicked us off our flight when a flt attendant overheard my husband expressing displeasure about flying w/ Trump,” he wrote.

3. JetBlue Confirmed That Goldstein & Lasner Were Kicked off the Flight

JetBlue has issued a statement, confirming that the Lasner and Goldstein were kicked off the flight and put on another plane.

The statement reads:

“The decision to remove a customer from a flight is not taken lightly. If the crew determines that a customer is causing conflict on the aircraft, the customer will be asked to deplane, especially if the crew feels the situation runs the risk of escalation during flight. Our team worked to re-accommodate the party on the next available flight.”

4. Goldstein Is a Lawyer Who Worked for the U.S. Mint in San Francisco

Goldstein is a lawyer who lives in Brooklyn with Lasner and their son. The State Bar of California attorney search shows that he was admitted to the State Bar of California in December 2002 and has been inactive since January 2012.

Before moving to Brooklyn, Goldstein was based in San Francisco, where he worked for the U.S. Mint as an Employee and Labor Relations Specialist, according to the International Ombudsman Association.

The Columbia College Today Winter 2012/13 issue mentions that Lasner and Goldstein married in Bolinas, California. Other members of the Columbia College 1996 class were at the wedding.

5. Goldstein’s Husband, Matthew Lasner, Who Once Called Trump ‘The Gordon Gekko of Developers’

According to his website, Lasner is an associate professor of urban studies and planning at Hunter College. He has written the book including High Life: Condo Living in the Suburban Century and edited Affordable Housing in New York: The People, Places, and Policies that Transformed a City with Nicholas Dagen Bloom. Lasner’s research focuses on “the history and theory of the U.S. built environment, with particular focus on housing and the relationship between ways of living and urban and suburban form,” according to his site.

Lasner earned a PhD from Harvard in 2007. At first, Lasner removed all tweets related to the Ivanka Trump incident form his Twitter page. However, he has since deleted his entire profile.

Lasner had made it clear that he was not a Donald Trump supporter, as the tweets below show.

In an interview with AM New York in March 2016, Lasner said that Trump represents “an ascension of ego, of surface, and of explicitly catering to new wealth” and nicknamed him “the Gordon Gekko of developers,” referring to the Wall Street character.

Lasner mentions in Affordable Housing in New York that he is married to Goldstein and they have a son, who was with the couple when they were on the flight.
