For example, she will often speak on the Be Best initiative which supports the well-being of children and fights against cyberbullying and drug use.
In the last few weeks, Melania has been making slightly different speeches when in public.
She recently attended an event for the Republican party convention which took place at the White House.
While at the event, Melania spoke about why she thinks her husband should be reelected.
Analysing the event, body language expert Judi James explained Melania’s role in the White House has grown in importance.
Judi also claimed that she appeared slightly nervous when addressing the crowds.
She told Express.co.uk: “The suggestion of the speech was that Trump’s team now cherish and value Melania’s impact and potential in a way that they never seemed to in the early days of the presidency.
“The way her arms pumped gently against her ribs in a self-motivating ritual, suggested that this promotion might not have been prompted by her though.
“Melania looks poised, elegant and rehearsed to within an inch of her life while Donald is all about spontaneity.”
Melania’s body language with Donald recently could suggest they have grown to have more of a shared role in the White House.
Judi added: “Melania also does stories and empathy and sympathy during her speeches. Donald now looks happy doing a little power and attention-sharing with his wife.”
Melania Trump: Five facts about the USA’s First Lady
Mum-of-one Melania can speak more languages than any other First Lady before her: English, French, German, Italian, Serbian and of course her mother tongue, Slovenian.
This also makes her the only First Lady whose first language is not English.
After Jacqueline Kennedy, Melania is the second First Lady who is a practising Catholic.
She met Pope Francis as part of a foreign tour with her husband and stepdaughter Ivanka.
Melania was a successful model, posing for Sports Illustrated, Vanity Fair, Vogue, Harper’s Bazaar and GQ.
Her skills aren’t confined to print, and she appeared in a commercial for Aflac, an American insurance company, in 2005.
Melania’s parents are Amalija Knavs and Viktor Knavs, and the couple live together in Washington.
She has one sister, Ines, who is reported to live in New York and work as an artist.
On May 7 2018, Melania launched her flagship campaign as First Lady, BE BEST, which The White House describes as “an awareness campaign focused entirely around the well-being of children”.
There are three main strands to the initiative: well-being, social media, and opioid abuse.
