President Donald Trump and First Lady Melania Trump unveiled their holiday card on Tuesday ahead of celebrating their first Christmas in the White House, but social media users have taken notice to the couple's eerily similar signatures featured upon it. The Trumps' signatures possess nearly identical zig-zag patterns as they wish receivers a "Merry Christmas and Happy New Year."

Melania's signature has been examined by speculators before, which has catapulted a string of conspiracy theories. Sheila Kurtz, a handwriting expert, told Yahoo in May that Melania's signature "looks just like his, which is absolutely amazing," but this is no coincidence as she suggests that it's "stylized" to resemble President Trumps.

Twitter users also took note of the similarities in the Trumps' signature style, which appeared to baffle many.

"Why is her signature the same zigzag as his," one user questioned in a tweet. Many Twitter commenters echoed this user's sentiment as they appeared to deem the Trumps' seemingly identical signatures as "weird," but others took the opportunity to poke fun at this finding.

The Trumps' holiday card has also come under scrutiny for lacking inclusivity. President Trump, Melania and Barron Trump signed off on a holiday card that wished recipients a "Merry Christmas," a message that differs greatly from the Obama family's holiday greeting. The Obamas' seasonal cards wished receivers a "Happy Holiday," which accommodated individuals that celebrate Christmas and those that don't.

This swap falls in line with Trump's campaign promise to bring back the phrase "Merry Christmas." The president first spoke of his desire for the phrase to reemerge in December 2016 to attendees at a rally in Michigan.

"Merry Christmas, everybody. Merry Christmas," Trump said. "Right? Merry Christmas. We're gonna start saying 'Merry Christmas' again."

The first family's holiday card follows Melania's reveal Monday of the White House's Christmas decorations. The decorations were designed by the first lady in honor of the 200 years of holiday traditions that have occurred at the presidential residence.

"The President, Barron, and I are very excited for our first Christmas in the White House," Melania said in a press release. "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 added.
