Fluoride in American tap water is nothing new. We've been safely adding it to our drinking water for decades and staved off tooth decay in our population.

But new skepticism has some Americans wondering about the benefits of the practice. This is in large part thanks to Robert F. Kennedy Jr., Donald Trump's pick to run the Department of Health and Human Services.

We discuss why fluoride is added to our water supply, the risks and benefits.

It was instrumental in coordinating global action during the pandemic. However, that meant became a target for the president of then and now.

The World Health Organization helps to protect and maintain the health of the world's population. It receives about 10 percent of its budget from the United States. President Donald Trump, however, doesn't see a lot of value in its work, signing an executive order Monday to withdraw America from the membership of the agency.

He called the organization "corrupt" and has accused it of taking more from the U.S. than it gives.

We discuss the future of global health without America at the table of one of its greatest proponents.

Social media bans for minors have been making the rounds internationally. Now, Congress is looking to follow that lead.

In November, Australia imposed a sweeping ban on social media for users under 16 years old. The ban holds social media companies responsible for enforcing age restrictions on their sites and prohibits minors under that age limit from using those platforms or creating new accounts.

The law doesn't name specific apps or websites, but companies could face fines of up to $32 million if they violate the ban.

We discuss how social media bans like Australia's are enforced and what it would take to pass similar measures in the U.S.

Humans love to connect. We're social like that. Whether we're sending telegrams, calling each other on the telephone, or DM'ing each other on the social media platform of our choosing, we're interacting.

Whether or not that constant connection is a good thing is another matter entirely. Writer and author Nicholas Carr spends a lot of time thinking about that very question (and others like it). His new book, "Superbloom: How Technologies of Connection Tear Us Apart," tells a story of the parallel rises of mechanical, efficient electronic communication and mass confusion.

But it's not just the fault of tech giants and social media companies. Carr encourages us to look inward and consider how our own psyches play a role. He joins us to talk about the realities of social media and constant connection.

It's a moment that's run through President Donald Trump's first week in office — a bishop in Washington imploring the incoming commander in chief to show mercy to the less powerful during a national prayer service.

This simple claim meant a lot to million worrying for the future of their country. It also offended many more who think it's on the right track.

But that hasn't caused Bishop Marian Budde to waver in her convictions.

She joins us to discuss her faith, what that moment meant to her, and what she hopes for the future of the U.S.

The first week of President Trump's new term ended with a late-night purge of around 17 federal inspectors general on Friday.

The exact total is still unclear. Trump said the move was a, quote, "very standard thing to do." But federal law requires a 30-day notification to Congress before inspectors general can be removed from their posts.

Also, in the first week of his second term – four Democratic-led states filed a lawsuit to stop President Trump's executive order to end birthright citizenship. On Thursday a federal judge in Seattle temporarily halted the implementation of the order, calling it, quote, "blatantly unconstitutional."

Our series, "If You Can Keep It," cuts through political noise to consider the state of our Democratic Republic and what matters to you.

We discuss the IG purge, take a closer look at the legal challenges to Trump's early moves, and how the Constitution guides our understanding of executive power today.

Donald Trump's first week back in office has been frenetic. The 47th president issued a slew of executive orders and actions on subjects ranging from immigration to diversity, equity, and inclusion programs.

And a Bishop made a heartfelt plea directly to the president and Vice President JD Vance, asking them to show mercy towards immigrants and LGBTQ youth.

Friday marks five days since the beginning of the first stage of the ceasefire between Israel and Hamas. And this week the Israeli Defense Force launched renewed raids into the city of Jenin in the Occupied West Bank, killing at least 12 Palestinians.

Pope Francis had strong words for Donald Trump as the president began to implement plans to target immigrants living in the U.S.

Despite campaign trail promises, the war in Ukraine did not end on the first day of Donald Trump's presidency. Ukrainian President Volodymyr Zelenskyy pondered this week whether Trump would even pay Europe much notice.

We get into all this and more during this week's News Roundup.

Tesla's Elon Musk, Meta's Mark Zuckerberg, and Amazon's Jeff Bezos were all in attendance Monday as President Donald Trump was sworn into office. In fact, they had better seats than most.

Tech Industry Titans have spent months cozying up to the 47th president of the United States. Musk made campaign appearances with Trump. Zuckerberg has switched up his cultural rhetoric to fall in line with the new administration. And Bezos's companies are investing in the first family.

Then there's TikTok thanking then President-elect Trump for signaling he'd keep the app around for Americans following its recent blackout (despite the app's ban being initially pushed by Trump himself).

We discuss the significance of these men working so closely with the new administration.

In his first moments as president, Donald Trump signed a flurry of executive actions targeting immigration. These include declaring a national emergency at the southern border and ending birthright citizenship.

The Trump administration also unveiled a plan to deploy as many as 200 Immigration and Customs Enforcement agents to conduct raids targeting undocumented migrants in cities across the country this week. And a memo from the Department of Homeland Security gives immigration enforcement officials the ability to enter schools and places of worship.In 2022, 11 million people were living in the U.S. without legal status.

We go over what Trump's immigration policies will mean for them — and what the fight to make them law will look like.

President Donald Trump issued a sweeping pardon of January 6 rioters within hours of taking office. The move came among dozens of other executive actions concerning things like remote work and immigration.

The president is making good on repeated promises for what aides called "shock and awe" on his first day. We break down what this slew of orders means for the U.S.
