Newlywed Bettina Trump marked America's 250th anniversary by celebrating the Fourth of July on the National Mall with family members Tiffany Trump and Kai Trump. Trump, 39, shared photos on Instagram from the holiday weekend gathering, which included President Donald Trump.

For the occasion, Bettina Trump wore a white strapless mini dress by Mara Hoffman, a piece featuring an intricate, folded neckline and a curve-hugging fit. The dress, which is no longer available, can be found on resale sites for up to $400. She accessorized her outfit with a $1,300 gold dove brooch by Schiaparelli and $895 Manolo Blahnik white silk heels. A white leather Hermès Kelly belt, valued at $1,375, completed her ensemble. Her hair was styled in a high ponytail.

In her Instagram post, Bettina Trump expressed her admiration for America and her father-in-law. She wrote, "4th of July at the National Mall with the President was America at its best: faith, freedom, strength, gratitude, and the unshakable belief that our country's greatest days are still ahead!" She also quoted President Trump, stating, "The President reminded us that NO dream in history is bigger than the American Dream and that from the patriots of 1776 to the heroes still pushing the final frontier… there is no place Americans can't go and nothing Americans can't do!"

The celebration also included an opportunity to meet the Artemis II crew, who had recently completed a mission circling the Moon, and Apollo 17 moonwalker Harrison Schmitt. Bettina Trump noted this as a reminder that "America does not just remember history… WE MAKE IT."

This recent event follows a family gathering at Camp David for Father's Day, where other Trump family members, including Ivanka, Tiffany, and Lara Trump, also spent time with President Trump. Activities during that weekend included shooting range sessions and shared campfire nights.

Bettina Trump became a member of the Trump family after legally marrying Donald Trump Jr. in May in Palm Beach. Their wedding was followed by a private celebration on Little Pipe Cay, an island where renting the main house costs $750,000 per week.
