In a room full of dignitaries on Inauguration Day, one guest stood out above the others. Barron Trump, the youngest son of Donald Trump, towered over the crowd as his father was sworn in as president of the United States. He certainly has grown since first moving into the White House in 2017.  When Trump first took office, Barron was 10 years old and in fifth grade. This time around he was old enough to vote for his father, with his mother Melania posting a photo of Barron casting his ballot on Election Day in November.
