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

During his inaugural address, Donald Trump announced that the nation’s “golden age” had begun, saying the United States “will flourish and be respected again all over the world” under his watch. The president also gave a veiled dig at his predecessor’s leadership, declaring, “America’s decline is over” during his speech.

The returning first lady and Barron Trump, the son she had once shielded from the public eye, used Monday’s inauguration to reintroduce themselves.
