Clay interviews Professor Mark Squillace of the University of Colorado Boulder's law school about the history and future of the National Monuments. When Congress created the National Monuments system in 1906, did they consider what the maximum size should be for a presidential proclamation of a new National Monument? Since a president can create a National Monument by executive order, can a later president reduce or eliminate that National Monument? Did the men who created the Antiquities Act understand that many National Monuments, like the Grand Canyon, would later graduate into full National Park status? With the Trump administration paring down some National Monuments, will a test case go to the Supreme Court to determine who, if anyone, has the authority to reduce the size of an already dedicated National Monument? And what was Theodore Roosevelt's role in our interpretation of the Antiquities Act? This episode was recorded on August 6, 2026.

Host David Horton asks Clay to discuss how two very different presidents, Theodore Roosevelt and Thomas Jefferson, viewed power. Both were ardent believers that the United States must control the North American continent. But Jefferson wanted to limit presidential power to ensure the legislative branch of the national government led on almost every public matter. Theodore Roosevelt was much more comfortable with power than Jefferson because he believed the 1787 Constitution was an outmoded, inefficient social compact for the problems of the 20th century. But even Roosevelt would have been startled by the idea of a Unitary Executive of essentially unlimited authority. Has the pendulum reached its limit, and are the people of the United States ready to move back toward regular order, or is the current flirtation with autocracy likely to become the new norm?

David Horton and Clay discuss the likelihood of a calm transfer of power during and after the November midterm elections. Does anyone believe there will be no allegations of election rigging, of votes by undocumented workers, or charges of election fraud in a few weeks? Time will tell, but Clay and David make a few careful predictions before the election. They also discuss Clay's recent cultural tour of Thomas Jefferson's France — Paris, Dijon, Nimes, the Pont du Gard, and the celebrated Canal du Midi that connects the Mediterranean and the Atlantic. France highly regards Jefferson as one of America's greatest ambassadors. Was the French Revolution in any way a cousin to the American Revolution a little more than a decade earlier? And why was Thomas Jefferson so cheerful about bloody revolution? This episode was recorded on October 17, 2026.

Host David Horton debriefs Clay on his recent cultural tour of the National Monuments of the Four Corners area. Clay teamed up with his friend Dr. Susan Ryan to visit Mesa Verde National Park, Bears Ears National Monument, and Canyon of the Ancients National Monument with a group of 20 participants from across the U.S. The goal was to explore the history and current status of America's National Monuments in the wake of President Trump's executive orders reducing the size of Bears Ears by more than 90%. Susan Ryan was an outstanding cultural tour lead, explaining how Southwestern archaeology is changing in the 21st century to show much greater respect for Indigenous communities. Clay performed as the 26th president, Theodore Roosevelt, and helped lead discussions of the 1906 Antiquities Act text and its several important ambiguities.

Clay Jenkinson gives four or five lectures annually for the Smithsonian Associates. In his most recent talk, he analyzed three notorious 20th-century censorship cases, all involving books once regarded as obscene. First, the case against James Joyce's novel Ulysses, thought by some to be the greatest novel of the century, went to trial in 1933. Second, the trial of D.H. Lawrence's Lady Chatterley's Lover in 1960, banned in England not just for its explicit sex scenes, but because the adulterous affair was between an aristocratic woman and a mere working-class gardener. And finally, Allen Ginsberg's Beat Generation poem Howl, published by City Lights Bookstore in San Francisco, was tried in 1957. Each case was full of dramatic twists, irony, and humor, and in each case a judge or jury decided these amazing works of literature were not legally obscene.

Author and explorer Denis Belliveau talks with Clay about his epic journey along the entire Silk Road in the footsteps of Marco Polo. Polo (ca. 1254-1324) traveled from Venice to the far end of China between 1271 and 1295 AD. He visited Kublai Khan in the legendary Xanadu. Denis Belliveau and his traveling companion, Francis O'Donnell, needed 70 visas to make the immense journey, none of it by airplane, much of it on foot, horse, camel, and such fortunate rides they could cadge along the way. They traveled with what Belliveau calls "reckless bravado and a lot of testosterone," through Turkey, Iran, Afghanistan, India, Tibet, and China, among other nations. They were, so far as anyone knows, the first people ever to retrace the entire Marco Polo journey. The result was a PBS documentary and excellent book, In the Footsteps of Marco Polo.

Host David Horton asks Clay Jenkinson what we have learned from the 9/11 attacks on the World Trade Center, the Pentagon, and all that has transpired since 2001. Clay offers six lessons — beware of overreacting; avoid endless wars that have little to do with the terror attack; keep your eye on the geopolitical ball and don't be distracted by temporary sex scandals; work harder to sustain the national unity that follows a catastrophe; Islam is not our enemy, and it is not the problem; and accept some responsibility for how American actions in the world frustrate and enrage others. Clay argues that America's isolation from Europe and the rest of the world has made us complacent about how our actions and policies inspire violent reactions.

Clay's conversation with historian Jim Rasenberger, the author of "A Perfect Coincidence: The Extraordinary Friendship and Astonishing Deaths of John Adams and Thomas Jefferson." Jefferson and Adams collaborated on the Declaration of Independence in 1776, served together as diplomats in France for the United States in the 1780s, and cherished each other's friendship. Then the heated politics of their time came between them, until by 1800, they were enemies. Fortunately, they patched their friendship back together when they were safely retired from public life and died on the same day, the Fourth of July 1826, in lovely harmony, one in Virginia, the other in Massachusetts. This episode was recorded on May 22, 2026.

Host David Horton interviews the third president of the United States, Thomas Jefferson, about the days and weeks following the Fourth of July 1776. How quickly did the printed texts of the Declaration circulate? What was the information network of the time that enabled most Americans to read the Declaration (or hear it read in public) within a few weeks? The final copy had to go to an engraver to become the beautiful presentation document we still revere today. At the time, the Founders did not know that the Declaration would become the most important document in the history of human liberty. Meanwhile, George Washington came very close to losing the war — and perhaps the independence movement — after getting bottled up by the British on Manhattan.

Clay interviews David Osborne, author of the 1992 bestseller Reinventing Government, about the challenges of the American public education system. How well are we preparing young people for the mid-21st century? Why is the United States slipping behind many other nations in educational metrics? David has spent the last few years focused on how we can reinvent public education. His new documentary film Turnaround: The Reinvention of the New Orleans Public Education System chronicles the astonishing success of charter schools in historically problematic school districts. How much does the survival of our republic depend on better schools for all Americans? This episode was recorded on April 27, 2026.

David Horton sits down with Clay Jenkinson to retrace a whirlwind summer of travel, history and adventure. Clay's journey began in May with a trek to ancient Troy and continued across the American West, following the trail of Theodore Roosevelt. Along the way came an unusual Independence Day in Italy, stops in Las Vegas and California, and a meandering journey along the Missouri River in the footsteps of Lewis and Clark.

Clay and David explore the history, surprises and memorable side trips that shaped the journey — and respond to questions and comments from listeners. This episode was recorded on August 6, 2026.
