Nancy Pelosi has been at the top of US politics for nearly 40 years - as the first, and only, woman in US history to serve as speaker of the House, she has played a central role in some of the most consequential American events of the last two decades, from the Iraq war to the US Capitol attack and Donald Trump’s impeachment.

In her latest book, “The Art of Power: My Story as America’s First Woman Speaker of the House” Pelosi gives a behind-the-scenes look at her formidable political career.

In this episode of The American Fourcast, she talks to Channel 4 News’s Matt Frei about what she’s learned about politics and power after nearly four decades in Washington, why Donald Trump is “dangerous” and what’s next for America as the Presidential election approaches.

Kamala Harris has chosen Governor Tim Walz as her Vice President for the 2024 Democrat ticket.

After considering nearly a dozen candidates, Harris landed on Walz who has been described as having the most "progressive record" of any of the other contenders.

Walz was an early supporter of the LGBTQ+ community, championed abortion rights into state law, and expanded free school meals & paid worker leave - so it’s not wonder the Trump-Vance team have branded him a “dangerously liberal extremist”. Rest assured, the animosity is mutual - Walz’s profile exploded after he called Donald Trump and JD Vance "weird".

Joining Matt Frei to talk about it in this episode of The American Fourcast are the UK Vice Chair of Democrats Abroad, John Scardino, the Chairman of Republicans Overseas UK, Greg Swenson, and the Director General for think-tank RUSI, Karin Von Hippel.

Vice President Kamala Harris is the favourite to be the Democratic nominee for president after Joe Biden’s shock decision to drop out of the race - but can she really beat Donald Trump?

Some polls suggest Kamala Harris is even less popular than Joe Biden, especially in the crucial swing states and like president Biden - she’s stumbled a few times in public - leading some to write her off - but has she been totally underestimated?

To discuss all this and more, Matt Frei was joined by Christina Emba, staff writer at The Atlantic, and Channel 4 News’ International Editor, Lindsey Hilsum.
