Dan Goldstein, Who Harassed Ivanka Trump on JetBlue Flight, Bragged About it on Twitter

If you're going to harass Ivanka Trump, her husband and children to the point where you get kicked off the flight, it's probably best not to brag about it on Twitter. Because when you do, everyone knows who you are.

"Your father is ruining the country. They ruin the country now they ruin our flight!" said Dan Goldstein to Ivanka, on a Jet Blue flight. Both the gay couple and the Kushner-Trumps had their children with them. Lasner also suggested Ivanka and her family should be on a private plane. For his words and attitude, Jet Blue removed Lasner and Goldstein from the flight.

Goldstein is employed in Brooklyn as an attorney. His partner, Matthew Lasner, who tweeted about the altercation, is identified as an Professor of Urban Studies at New York's Hunter College. Just don't call them liberal elitists, k?

When Goldstein decided to take on Ivanka Trump and Jared Kushner, he also took on Trump Supporters.

"While Ivanka could very well take a private jet, she chooses a commercial fight to show the American people she isn't entitled unlike other celebrities and politicians, but then she is subjected to these disgusting bullies and their behavior. Shame!!!" posted Lori B.

"The left are so understanding & Peaceful they had to harass a young lady a& her child, what's really important? said Lawrence O

"Personally, I don't care if they're gay, black or purple with polka dots ..... a woman with her children should be untouchable no matter who their father are" said Lori A...

"They should be jailed and pay huge fines! Attacking a woman and her children! Shame on them!" said Betty H.

"Idiocy at its best," said Michael F.

It's noteworthy that the entire scene played out in "The Bubble," the part of the Country that went decidedly for Hillary Clinton and against Donald Trump. The two men were so confident that they would suffer no harm for harassing the President Elect's oldest daughter, that they identified themselves on Facebook and Twitter.

Ivanka Trump and her husband Jared Kushner were on a flight at JFK Airport in New York Thursday, when a passenger confronted them, said Matthew Lasner, who tweeted about the encounter between his husband and the couple.

"Ivanka and Jared at JFK T5, flying commercial. My husband chasing them down to harass them. #banalityofevil," Lasner said in a now-deleted tweet.

Lasner said in another deleted post that his husband "expressed displeasure in a calm tone" about Trump and Kushner's presence on their flight when "JetBlue staff overheard, and they kicked us off the plane." Can you imagine? Lasner also tweeted a photo appearing to show Ivanka on the flight.

JetBlue said in a statement that "The decision to remove a customer from a flight is not taken lightly." Neither was the decision to fly coach, which I'm sure Trump and Kushner will never do again.

"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," the company said in the statement. "In this instance, our team worked to re-accommodate the party on the next available flight."

Passenger Marc Scheff told NBC News he witnessed the incident before the plane took off. Scheff said Lasner's husband was agitated and began making comments.

"The comments were definitely for everyone but he was directing them towards her," he said.

In a post on Facebook, Scheff said he and his son were featured in the photo that appeared to show Ivanka Trump on the flight. Scheff wrote that the passenger who addressed Trump did not accost her directly and did not yell. "He was also not what I would describe as calm. Agitated maybe," he said in the post. Lasner remained calm throughout the incident, he added.

Scheff wrote that Lasner's husband exclaimed "they ruin the country now they ruin our flight!" The flight was delayed because the Trump family needed to get on first through different a different area than the other passengers, he said.

"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,'" Scheff wrote.

Ivanka and Jared Kushner and their family were on the way to Hawaii by way of Florida. The Secret Service confirms she is under their protection at all times, including during the flight.
