Barron Trump appears at the inauguration months after his father gave the teen credit for helping to identify popular podcasters on the campaign trail.

He is the youngest son of the 78-year-old politician, and the only child of Trump's wife Melania, 54. In all of the family photos, however - which also include Trump's eldest children, Donald Jr, 46, Ivanka, 43, Eric, 41, Tiffany, 31 - Barron can be seen towering over both his siblings and his parents.
