She also shared pictures from inside the White House following the event.
The message said: “Today, on the 41st anniversary of Pope John Paul Il’s first pilgrimage to Poland, @realdonaldtrump signed an Executive Order supporting International Religious Freedom.”
Melania dressed for the sombre occasion by wearing head-to-toe black.
The First Lady stuck with her signature style and wore a sleeveless fit and flare midi dress.
This is a look she will often choose when stepping out with Donald.
The sleeveless tuxedo dress had a v-neckline and buttons down the front of the garment.
It flared out into a full pleated skirt that cut off just below her knee.
The First Lady opted for a glamorous make-up look with dark eyeshadow and lashings of mascara.
The appearance follows a quiet couple of months from Melania as she has been keeping a low profile during the coronavirus lockdown.
However, she has been spotted out more often as lockdown restrictions start to relax in some parts of the United States.
She will often show off fashionable pieces from her designer wardrobe.
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.
