Scourge of Our Time – The synthetic opioid fentanyl was designed to help patients in unbearable pain. But after making its way from hospitals to communities in every corner of the country, it has ignited the worst drug crisis in U.S. history, killing more than 70,000 Americans last year alone. Bill Whitaker investigates the root causes, from prescription opioids peddled by some of America's largest drug companies to the Mexican cartels' takeover of the illicit fentanyl market, and questions top U.S. officials about what's being done to stem the deadly tide. The Trustbuster – Lesley Stahl interviews the youngest-ever chair of the Federal Trade Commission, Lina Khan. The powerful and polarizing trustbuster discusses her determination to enforce antitrust policies as part of the Biden administration's breaking away from 40 years of a hands-off approach.  Inside the Archives – After former President Donald Trump and then-Vice President Biden held onto documents that should have been turned over to the National Archives, the small federal agency that is supposed to safeguard America's past was thrust into the national spotlight. 60 MINUTES spent several months inside the Archives, where Norah O'Donnell was granted rare access not just to the nation's founding documents, but restricted vaults and priceless artifacts, including Revolutionary War-era oaths of allegiance signed by George Washington and Alexander Hamilton, Adolf Hitler's will and President Nixon's resignation letter. O'Donnell also spoke to the recordkeepers responsible for preserving presidential papers about why that mission is so vital. The story covers the Archives' past, present and also contains some news about a major change in its future: the Emancipation Proclamation and 19th Amendment will go on permanent display in the Archives' Rotunda in Washington in 2026, joining the Declaration of Independence, Constitution and Bill of Rights in time for America's 250th birthday. Keith Sharman and Roxanne Feitel are the producers.
