President Donald Trump's youngest son turned 19 on Thursday, with sources describing Barron Trump as an "old soul" with "old world manners" despite his young age, according to People magazine.
Barron is the only child of the president and First Lady Melania Trump, and he mostly remained out of the spotlight before his May high school graduation. Since then, he has made his presence felt by appearing at Trump rallies, including one on Inauguration Day, where he basked in the crowd's applause.
