A video of Barack Obama's eldest daughter, Malia, blowing smoke rings went viral on Friday (24 November).
It was shared on the conservative news website the Daily Caller after it was uploaded to the Instagram page Barstool Sports.
Many people condemned the website's decision to publish the story.
Lawyer Mark Yzaguirre commented on Twitter: "The Daily Caller has nothing better to do than hassle a college student."
Another Twitter user described the article as "unacceptable."
"Like I said, whether Republican or Democrat, adults or minors, unless they have inserted themselves into politics, they should be off limits. Respect their right to privacy. They did not ask for any of the attention," she wrote.
Since her father left office and she started at Harvard University, Malia Obama has been subjected to intense media scrutiny.
The former first daughter was also recently photographed kissing another Harvard student at a football game.
Both Ivanka Trump and Chelsea Clinton also jumped to the freshman's defence.
They took to social media to blast the news coverage and called on people to respect the 19-year-old's privacy.
Trump tweeted: "Malia Obama should be allowed the same privacy as her school aged peers. She is a young adult and private citizen, and should be OFF limits."
Shortly afterwards, Clinton wrote on Twitter: "Malia Obama's private life, as a young woman, a college student, a private citizen, should not be your clickbait. Be better."
