PALM BEACH—The FBI searched Donald Trump’s Mar-a-Lago estate on Monday as part of an ongoing investigation into the former president's 16-year-old son Barron. Federal agents have long suspected that Barron's growth to the towering height of 6 feet 7 inches has involved the use of controlled substances. People familiar with the matter say that the FBI seized a large stash of so-called "Tall Pills," which are not FDA-approved and are manufactured in an unknown foreign country. Importation of unapproved drugs is a violation of the Federal Food, Drug, and Cosmetic Act, and legal experts say that Barron could face a term of incarceration in a juvenile detention facility, where is likely to face many entreaties to join the basketball team.
