Donald Trump and Kamala Harris met on stage for their first, and likely only, debate of the campaign Tuesday night, just a week before early voting kicks off in Pennsylvania, one of the most critical battleground states of the election.

Over an hour and a half Harris needled Trump on everything from crowd sizes to getting “fired” by the American people.

With each jab the former president seemed to become more enraged, his anger distracting him from his own talking points and allowing Harris to set the agenda.

Headlines across the country declared a clear victory for Harris and Trump now says that he will not debate her again. 

But how much will all this matter at the polls? The New Yorker’s Susan Glasser joins Diane to help answer that question.  

Donald Trump began his political career with demands to see Barack Obama’s birth certificate, based on the false claim that the he had been born outside of the United States. In other words, a lie. 

The former president concluded his term in office with an even bigger lie, namely that the 2020 election was rigged. 

In between, Trump fibbed thousands of times about things big and small. And keeping track of these mistruths and exaggerations were political fact-checkers, journalists whose job it is to call out not only Donald Trump’s lies – but the lies all politicians tell. 

Glenn Kessler has been the chief writer and editor of the Fact Checker column for The Washington Post since 2011. In it he examines the “truth behind the rhetoric.”

Kessler joined Diane to talk about how his job has changed since Donald Trump entered politics and the challenges of covering the 2024 presidential election. 

If you’re a reader of the New York Times – or a lover of books – you might know about the paper’s project this summer counting down the top hundred books of the century so far. 

Number one on the list? “My Brilliant Friend” by Elena Ferrante. It is the first of four novels that tell the story of the friendship between Lila and Elena, two working class girls growing up in post-World War II Naples. In 2018 HBO adapted the series for television. 

Diane hosted a discussion of “My Brilliant Friend” as part of her Readers Review series back in 2015 on The Diane Rehm Show. She and her guests dug into the characters, the setting, and the mystery surrounding the author’s identity. 

Diane's guests included Maureen Corrigan, book critic for NPR's Fresh Air, and The Nicky and Jamie Grant Distinguished Professor of the Practice in Literary Criticism at Georgetown University; Louis Bayard Author, "Roosevelt's Beast." His other books include "The Pale Blue Eye," "The School of Night" and "Mr. Timothy," a New York Times Notable Book. He teaches fiction writing at The George Washington University; and Professor of contemporary Italian culture, Georgetown University; author of "The Tigress in the Snow: Motherhood and Literature in Twentieth-Century Italy" and of the novel "Un Paese Di Carta."

Kamala Harris currently leads Donald Trump in national polls by more than 3 percentage points according to the website 538. But if there’s one thing that recent elections have taught us, it is that a victory in the popular vote does not guarantee a spot in the oval office. 

This is, of course, thanks to the Electoral College. 

In two of the last six elections, more Americans punched their ballots for the eventual losers than the men who went on to claim the presidency. 

And the same could happen again this year.  

“My opinion is that it is a fundamentally unfair system because of the way it erases so many millions of Americans’ votes,” says Jesse Wegman, a member of the editorial board of the New York Times.  

In 2020 Wegman joined Diane to talk about his book, “Let the People Pick the President,” and made his case for abolishing the Electoral College. With the 2024 election less than 75 days away, we revisit their conversation. 

If you count yourself among the majority of Americans who own at least one pet, you might have noticed that your vet bill is quite a bit bigger than it once was. In fact, over the last decade the cost of pet care has risen by more than 60%.

Helaine Olen is a journalist who has written about personal finance and the financial industry for years. In 2020, her aging dog fell ill, and she found herself shelling out big bucks to keep her beloved pup alive. 

She knew she wasn’t the only one who was willing to open her wallet in a big way for her furry friend and started looking into the big business of veterinary care. What she found was an industry going through a major shift, with a flood of private equity investment and corporate consolidation. 

Olen joins Diane to discuss what she says can be called the era of Big Vet. 

Dr. Anthony Fauci became a household name during the Covid-19 pandemic. 

To many, he was a hero for his efforts to relay potentially lifesaving information. But he also found himself at the center of conspiracy theories -- and became the target of a vitriolic political backlash. 

He says of the experience that it was “very painful and tragic to see people make decisions that led to their detriment.”

Dr. Fauci served as director of the National Institute of Allergy and Infectious Diseases from 1984 to 2022. He has advised seven presidents, guiding the nation’s response to threats like Zika, Ebola, AIDS, and Anthrax.  His work on a 2003 plan to address the global HIV/AIDS crisis helped save more than twenty-five million lives. 

Dr. Fauci’s new memoir is titled “On Call: A Doctor’s Journey in Public Service”.  He joins Diane to talk about his career in public health and share his thoughts on the threats ahead. 

President Biden laid out a series of proposals to change some fundamental aspects of our nation’s highest court this week. This included term limits, a code of ethics and a constitutional amendment that would say nobody is above the law. 

Though the Supreme Court’s approval ratings are stuck at historic lows, Republicans said the reforms are “dead on arrival.” Democrats, on the other hand, see this as a winning issue among the American public for this election cycle, and beyond. 

“I think Biden and the people advising him are playing the long game,” says Harry Litman. 

Litman is the senior legal affairs columnist at the Los Angeles Times, a former U.S. attorney and deputy assistant attorney general, and host of the podcast “Talking Feds.” He joined Diane to break down Biden’s proposed reforms, what impact they would have, and why the president is proposing them now. 

You can find "Talking Feds" wherever you listen to podcasts or on YouTube. 

For years experts have warned of a wave of politically motivated violence in America. And, some might argue, that threat of violence has become a reality. 

There were the events of January 6th when one woman was killed, police officers were beaten, and the Vice President Pence’s life threatened. There was the foiled kidnapping plot against Michigan Governor Gretchen Whitmer that ended in multiple convictions. And there was the recent assassination attempt of Donald Trump, when bullets narrowly missed ending the former president’s life. 

“You certainly see by every possible measure that it’s worsening,” says Adrienne LaFrance, executive editor of The Atlantic. 

LaFrance has written extensively about political violence in the U.S. She joins Diane to talk about her new essay titled “American Fury,” in which she asks if the situation will get worse before it gets better. 

The Republican National Convention convention wrapped up last night with a speech from Donald Trump that lasted more than 90 minutes. It capped a week that was heavy on rhetoric, short on specifics. 

Enter Project 2025. If you haven’t heard of it, it’s a document created by the conservative Heritage Foundation that lays out a vision for the next Republican president. 

“Project 2025 has gotten a lot of attention,” says Andrew Prokop, a senior political correspondent at Vox. He notes that Democrats in particular point to it as “a stand in for a lot of Trump’s extreme plans for dictatorship.”

Though Trump has distanced himself from the document, experts say much – or even most of its proposals will likely be on the agenda for a possible second Trump term. 

Andrew Prokop joined Diane to talk about the myths and the facts about Project 2025. 

Sheila Johnson is known as the nation’s first black female billionaire. She first rose to prominence as the co-founder of Black Entertainment Television, or BET. Since then, she has become a widely recognized business leader, a hotel mogul, and the co-owner of three professional sports teams. 

But, Johnson says, her triumphs masked deep trauma and pain that she carried for decades. That included fear and self-doubt, an emotionally abusive 33-year marriage, and a severe depression following her divorce. 

Johnson joined Diane in April at WAMU’s Black Box Theater for a special in-person Diane Rehm Book Club Conversation. They talked about her memoir, “Walk Through Fire.”
