Whistleblower: A person who exposes secretive information or activity within a private or public organization that is deemed illegal, unethical, or not correct. Like a referee blowing their whistle when they see a foul on the soccer field.
Vietnam War: A long, costly armed conflict between communist North Vietnam and South Vietnam, which had U.S. support. It's like an intense tug-of-war match with teams pulling for years before one side finally falls.
Executive Privilege: The right of the president to withhold information from Congress or judiciary to protect national security. Imagine this as your older sibling hiding their report card from you because they say it's "none of your business."
