Barron Trump's playful moment with his sisters Ivanka and Tiffany after Donald Trump's inauguration

Barron Trump had a sweet moment with his half-sisters, Ivanka Trump and Tiffany Trump, following their dad, Donald Trump's inauguration at the US Capitol in Washington D.C. on Monday. The 18-year-old NYU-Stern student smiled during a playful moment with his siblings while the pair posed for a photo.

Barron, the tallest of his siblings, stood behind Ivanka and Tiffany, and their sister-in-law Lara Trump, who is married to Eric Trump. The three of them smiled for a photo without them noticing that Barron was standing behind them. 

A viral video shared on social media showed the moment when Ivanka turned around after the photo was taken and noticed Barron standing behind them and laughing. Ivanka, Tiffany, and Lara looked surprised. "Oh!" Ivanka can be heard saying while playfully patting Barron. "That's the best!"

All the Trump siblings were present at the inauguration ceremony, witnessing their dad being sworn in as the 47th president of the United States. Barron looked elegant in a classic suit for the special occasion. 

He stepped out in a long black overcoat, white shirt, and navy blue tie, to attend a church ceremony in St John's Episcopal Church ahead of the inauguration. He looked happy to support his dad as he stood next to his mom, Melania Trump.

Barron is set to continue his studies in New York City. However, he will be visiting Washington D.C. “I think he will come and visit,” Melania said to Fox during a recent interview. She also said she would be dividing her time as needed, supporting her son every step of the way.

“I will be in the White House. And when I need to be in New York, I will be in New York,” Melania said. “When I need to be in Palm Beach, I will be in Palm Beach. My first priority is to be a mom, to be a first lady, to be a wife.”
