Donald Trump and Ivanka Trump's relationship is not simply as a father and daughter. A body language expert said the president treats his eldest daughter like his direct heir, unlike his other children. 

When Donald Trump took an oath of office, Ivanka moved to Washington D.C. with her husband, Jared Kushner, and their children. In her new book The Art of Her Deal: The Untold Story of Melania Trump, author Mary Jordan revealed that Ivanka even tried to rename the Office of the First Lady during the early days of the Trump administration but Melania Trump blocked her stepdaughter's plan. 

While Melania has been keeping a relatively low profile as First Lady of the United States, Ivanka plays a prominent role in her father's administration. The 38-year-old former model was given a special role as advisor to the president, unlike her other siblings. 

As senior advisor to POTUS, Ivanka often represents the presidents, and even the American people, in official events. Body language expert Judi James said this only shows how important Ivanka is to the Trump administration. 

James told Express said there seems to be an emphatic sense of "public" posing between POTUS and Ivanka, which also defines them as a power duo. She analyzed one of the photos of the father and daughter tandem. 

She said, in the picture, the way the president held both Ivanka's hands signals the idea that Trump displaying his "direct heir that he trusts, promotes, and endorses." James added that Trump's smile showed pride and also seemed to convey the message that no one can upset Ivanka because it will also upset him. 

The photo that James was referring to was taken in March 2019 at the White House when the president hosted a meeting with Apple CEO Tim Cook to discuss revamping the American workforce. During the press briefing, the president showed off his close relationship with his daughter as he laughed and joked with her. 

James said how the president treats Ivanka is different from his youngest daughter Tiffany. She said, with the 26-year-old socialite, Trump's body language is more like he is just being a father than he is promoting a dynasty like with Ivanka. 

Meanwhile, many also believed that there has been a competition between the two Trump women at the White House: Melania and Ivanka. When Melania resisted to immediately move to Washington D.C. after her husband won over Hillary Clinton in the 2016 elections, Ivanka Trump, apparently, used her influence. Aside from trying to rename the First Lady's Office to "First Family Office," she also, reportedly, treated the private residence as if it were her own home.
