Clay welcomes Pulitzer Prize-winning historian Joe Ellis to the program to discuss America at 250. Ellis is the author of more than a dozen books about the Early National Period. He has been in several Ken Burns documentaries and a wide range of other media projects. Ellis believes the American republic is in grave danger and could still collapse. Still, he hopes that the American people are waking up to the threat to their now-fragile constitutional order. Clay and Joe examine the debate between Thomas Jefferson, who believed in the goodness of humankind and our ability to govern ourselves rationally, and John Adams' view that human nature crossed the Atlantic Ocean with the colonists of the 17th century, and that human passions and selfishness must be factored into any political system that can survive in the long run.

Host David Horton interviews the third president, Thomas Jefferson, about the circumstances surrounding the writing of the most important document in American history. Arguably the most important document in human history. Jefferson insisted that he was only trying to articulate what every American was thinking in the early summer of 1776. David Horton asks Mr. Jefferson to read the entire text of the Declaration, including the 27-point indictment of King George III and the Parliament of England. Jefferson always reminds us that if the other Founders had known how famous this document would become, Jefferson, just 33, and the youngest member of the Virginia delegation to the Continental Congress, would probably not have been chosen to write the Declaration.

Clay welcomes one of his favorite guests, Dr. Lindsay Chervinsky, to talk about America at 250. Many Americans are bewildered and frightened by the current state of the Union, unsure how things got so partisan and paralyzed. Instead of offering our personal opinions on the current crisis, we, as historians, attempt to contextualize the present moment within the broad sweep of American history, beginning, of course, with the Founding Fathers. What would Adams and Jefferson say about the world of 2026? Would they be disappointed with us? And what would they urge us to reform as we move forward into the next fifty, one hundred, and two hundred fifty years? And Clay asked Lindsay to point to the Golden Age of American life. You may be surprised by her answer.

Clay interviews Peter Stark, the author of a new book on the 1540 exploration of what would eventually become the United States by Spanish Conquistador Francisco Coronado. The Lost Cities of El Norte is a remarkable examination of an expedition that took place 250 years before Lewis and Clark. The book chronicles Coronado's search for the famed Seven Cities of Cibola, rumored to house untold wealth somewhere in the American Southwest. Coronado's ambitious expedition, one of the largest ever of the New World, traveled as far north as present-day Kansas. Although Coronado pledged to treat indigenous people with respect, that humanitarian impulse soon broke down. But the good news is that the indigenous Puebloan people outfoxed him at every turn, representing one of the earliest successful attempts at native resistance to European imperialism. Stark's previous book, Astoria, told the story of the American fur trade after the Lewis and Clark Expedition. This episode was recorded on May 20, 2026.

From Devils Tower in northwestern Wyoming, Host David Horton and Clay Jenkinson discuss Theodore Roosevelt's conservation achievements. When the National Monuments and Antiquities Act was passed in 1906, President Roosevelt lost no time in setting aside what would become 18 National Monuments, starting with Devils Tower just west of the Black Hills. Roosevelt had little to do with the creation of the Antiquities Act, but he made the most of it, culminating in his colossal designation of Grand Canyon National Monument in 1908. In the course of his two-term presidency, Roosevelt set aside a whopping 230 million acres of National Park, National Forest, National Monument, National Wildlife Refuge, and National Game Preserve. No president has done more. David asked Clay to outline his three-phase Roosevelt conservation tour for 2026. First, South Dakota, Wyoming, and Colorado; later, Montana and Idaho; and in the fall, all of Roosevelt's conservation designations in the Four Corners region of the Southwest.

Clay and his frequent guest, the redoubtable Lindsay Chervinsky, discuss books written about Jefferson's declaration, arguably the most important document in the history of liberty. Among the titles discussed are Walter Isaacson's recent The Greatest Sentence Ever Written, which celebrates the preamble of the Declaration of Independence, to Garry Wills' award-winning 1978 Inventing America, which locates the inspiration in the Scottish Enlightenment, and Pauline Meier's 1997 American Scripture: Making the Declaration of Independence, which examines local and regional declarations that contributed to Jefferson's great national document. Could any of the other Founding Fathers have written so magnificent a declaration? What role did Jefferson's famous "felicity for expression" play in the historical fame of America's mission statement?

Host David Horton interviews Thomas Jefferson about freedom of expression in America. Did the Founding Fathers know what they were doing when they ratified the extraordinary First Amendment of the Constitution? What limits, if any, should there be in the expression of ideas in a free society? When, if ever, can government suppress press freedom? What protections do American citizens have against malicious attacks on their character? When Jefferson retires and humanities scholar Clay Jenkinson takes the microphone, Horton asks Clay about the final episode of Stephen Colbert's Late Show, which among other things, gave Paul McCartney the last word with a fabulous rendition of the Beatles song "Hello-Goodbye."

Clay interviews Craig Fehrman, the author of an important new book on Lewis and Clark, This Vast Enterprise: A New History of Lewis and Clark. Fehrman approaches the great story of the Lewis and Clark Expedition by viewing it through the eyes of the often-overlooked participants: Sergeant John Ordway, Clark's enslaved valet York, and Sacagawea. Rigorously researched and grounded in actual historical discoveries, this book will be essential reading for students of the Lewis and Clark Expedition. In his footnotes, Fehrman begins with a truly remarkable short essay on his methods and historiography. These essays, which amount to 40,000 words, are alone proof that his work needs to be taken seriously. And he's great fun to interview. This episode was recorded on April 9, 2026.

Clay's conversation with Italian journalist Marzio Mian about his new book, Volga Blues: A Journey into the Heart of Russia. Mian and his photographer spent four weeks following the Volga River from its source northwest of Moscow to its mouth on the Caspian Sea. The Volga River is considered the mother and the flowing heart of Russia. Traveling by car with two sometimes dubious Russian guides, Marzio and his partner attempted to stay below the radar of the paranoid Russian government, now grinding through its fourth year of war against its neighbor, Ukraine. In this extraordinary interview, Marzio explains that the Russian people don't see the world as we do in the West. They believe they are fighting a defensive war in Ukraine against NATO, Europe, and the U.S., defending the sacred homeland from western aggression, territorial ambition, and cultural decadence. His goal was to encounter ordinary Russian people, to learn how they see the war in Ukraine, how they view Vladimir Putin now, in the 26th year of his dictatorship, and how they regard the Volga River, the spiritual artery of an ancient and mysterious civilization.

Guest host David Horton interviews President Thomas Jefferson about his strong anti-royalist principles. In the Declaration of Independence, Jefferson lambasted King George III for his crimes against the American colonists. Jefferson did not go quite as far as Thomas Paine, who called George III "the royal brute of England," but he wanted to eliminate all echoes of monarchism in American public life. Jefferson met George III once in 1786 and came away even more disillusioned than he had been previously with the ways of kings. In France, he met Louis XVI several times and generally liked him, but found him woefully out of touch with the suffering of the great mass of French people. David Horton wondered how Mr. Jefferson would react to the American fascination with British royalty in our time. This episode was recorded on April 28, 2026.
