President Joe Biden is being threatened with impeachment by the Republican-led U.S. House of Representatives. His predecessor, Donald Trump, was twice impeached by a Democratic-led House. Three presidents earlier, Bill Clinton was impeached. No president has ever been removed from office as the result of an impeachment, but it continues to be a high-profile way to go after the president of the United States.
But what exactly is impeachment? Why is it included in the U.S. Constitution? How does the process work?
Constitutional scholar Michael Gerhardt offers a comprehensive, nonpartisan, and up-to-date explanation of the Constitution’s various mechanisms for holding presidents accountable for misdeeds real and imagined. He is the author of the new book The Law of Presidential Impeachment, which draws on a lifetime of scholarly research, as well as Gerhardt’s unique experience as a witness and consultant in the impeachment trials of Bill Clinton and Donald Trump.
Join us as Gerhardt offers new perspectives on impeachment, arguing that it cannot be properly understood in a vacuum, but must instead be viewed in the context of its coordination with such other mechanisms as criminal prosecutions, censure, elections, congressional oversight, and the Fourteenth and Twenty-Fifth Amendments.

Three decades after the end of the Cold War, the United States finds itself in a volatile rivalry with the other two great nuclear powers—Xi Jinping’s China and Vladimir Putin’s Russia—in a world far more complex and dangerous than that of half a century ago.
New Cold Wars—the latest from the Pulitzer Prize–winning journalist and bestselling author David E. Sanger—is a fast-paced account of America’s plunge into simultaneous confrontations with two very different adversaries. For years, the United States was confident that the newly democratic Russia and increasingly wealthy China could be lured into a Western-led order that promised prosperity and relative peace—so long as they agreed to Washington’s terms. By the time America emerged from the age of terrorism, it was clear that this had been a fantasy.
Sanger says now the three powers are engaged in a high stakes struggle for military, economic, political, and technological supremacy, with nations around the world pressured to take sides. Yet all three are discovering that they are maneuvering for influence in a far more turbulent world than they imagined.
Based on an array of interviews with top officials from five presidential administrations, U.S. intelligence agencies, foreign governments, and tech companies, Sanger confronts the era’s critical questions: Will the mistakes Putin made in his invasion of Ukraine prove his undoing and will he reach for his nuclear arsenal—or will the West’s famously short attention span signal Kyiv’s doom? Will Xi invade Taiwan? Will both men deepen their partnership to undercut America’s dominance? And can a politically dysfunctional America still lead the world?
From the battlefields of Ukraine—where trench warfare and cyberwarfare are interwoven—to the Taiwan headquarters where the world’s most advanced computer chips are produced and on to tense debates in the White House Situation Room, Sanger will explain America’s return to superpower conflict, the choices that lie ahead, and what is at stake for the United States and the world.

David Sanger: China's Rise, Russia's Invasion, and America's Struggle to Defend the West

In the early 1990s East Palo Alto was referred to as the “murder capital” of the United States. Thirty years later, the city has its youngest-ever mayor and has undergone a complete transformation, with zero homicides recorded in 2023. Mayor Antonio López believes that civics education and the energy of young people are keys to the continued growth of his city.
Mayor López, in conversation with Commonwealth Club World Affairs’ own Issabella Romo, talks about the role of a mayor, his path into politics, and how being a poet has shaped his leadership style. Mayor López talks to students about upcoming elections, the importance of civic discussion, and why young people matter in a democracy.
 
This program is part of the Commonwealth Club World Affairs’ civics education initiative, Creating Citizens.

Antonio López: Civic Leader, Poet, and Mayor of East Palo Alto

Batteries are a critical part of the transition away from fossil fuels. From electric vehicles to grid scale storage for wind and solar, demand for batteries is expected to grow 500% by 2030. In order to meet that demand, we’re going to need a lot more batteries. 
And while companies like JB Straubel’s Redwood Materials are building capacity for recycling, for now that means a lot more mining. With the battery supply chain only growing more critical as the electric vehicle market matures, we’re revisiting this critical episode from last summer exploring how to build a battery supply chain that meets demand while reducing harm.
Guests: 
JB Straubel, Founder and CEO, Redwood Materials 
Aimee Boulanger, Executive Director, Initiative for Responsible Mining Assurance

CLIMATE ONE: REWIND: Building a Better Battery Supply Chain with JB Straubel and Aimee Boulanger

Scientists have known for decades that climate change is an existential crisis. For just as long, critics say there has been a complete failure of our institutions to rise to the challenge. Governments have struggled to meet even modest goals. Fossil fuel interests maintain a stranglehold on political and economic power. Even though we have seen growing concern from everyday people, civil society has succeeded only in pressuring decisionmakers to adopt watered-down policies. All the while, the climate crisis worsens. Is there any hope of achieving the necessary systemic change?
Dana R. Fisher argues that there is a realistic path forward for climate action―but only through mass mobilization that responds to the growing severity and frequency of disastrous events. Spurred by the lack of progress, climate activism has become increasingly confrontational. Fisher examines the radical flank of the climate movement: its emergence and growth, its use of direct action, and how it might evolve as the climate crisis worsens. She considers when and how activism is most successful, identifying the importance of creating community, capitalizing on shocking moments, and cultivating resilience. Join us as Fisher offers timely insights on how activist social movements can take power back from deeply entrenched interests and create transformative climate action.
