"Merry Christmas from President Donald J. Trump and First Lady Melania Trump," reads the tweet revealing the portrait.
"The President, Barron, and I are very excited for our first Christmas in the White House," said First Lady Melania Trump.
"As with many families across the country, holiday traditions are very important to us. I hope when visiting the People's House this year, visitors will get a sense of being home for the holidays."
"On behalf of my husband and Barron, I want to wish everyone a Merry Christmas and joyous holiday season," the First Lady said.
The use of the holiday greeting in the tweet is keeping with the president's campaign pledge to start saying 'Merry Christmas again."
The Obamas never used the word "Christmas" on any of their eight Christmas cards.
In 2009, the Obamas' Christmas card said "Season's Greetings." During other years, the cards frequently used the word "holiday."
On Monday, the White House unveiled its Christmas decorations. The theme of this year's decorations is "Time-Honored Traditions."
Mrs Trump designed the theme to pay respect to "200 years of holiday traditions at the White House," according to her office.
A promotional video from the White House showcasing this year's decorations zoomed in on a traditional nativity set featuring a baby Jesus wearing a crown.
