What can humans learn about ourselves from studying chimpanzees? Primatologist Frans de Waal has spent almost three decades studying the behavior and intelligence of chimpanzees. Now, he’s focused on their emotional lives--and he’s found primates and people aren’t so different in how they react to circumstances and each other. Jeffrey Brown talks to de Waal about the implications of his findings.

Gloria Steinem is a writer, author, activist and feminist icon who travels widely to raise awareness for the gender equity causes she helped pioneer. At age 85, Steinem says she has no intention of passing on her torch but instead will use it to light others'.

In our news wrap Wednesday, President Trump vowed to fight congressional Democrats all the way over the series of investigations and subpoenas targeting those in his close circle. He called the investigation efforts “nonsense.” Also, the UN reports that Afghan and International forces killed more Afghan civilians in the first three months of this year than insurgents did, reversing recent trends.

In Sri Lanka, investigators have learned more about the Islamist militants they blame for a series of Easter Sunday bombings. At least 58 people have been arrested, many of them from well-off Sri Lankan families whose neighbors expressed shock at their apparent involvement. The death toll from the attacks now stands at 359. Debi Edward of Independent Television News reports from Colombo.

Although the Mueller report concluded Russia intervened in the 2016 election in a “sweeping and systematic fashion," the Trump administration has at times downplayed the interference, as well as 2020 election security. Judy Woodruff asks former Homeland Security official Juliette Kayyem and Thomas Rid, author of a forthcoming book on influence campaigns, about what has and hasn't been done.

The Rohingya people of Myanmar have long been persecuted by their government, primarily for their Muslim faith amid a Buddhist majority. A million of them have fled the violence to camps in neighboring Bangladesh, which is tiring of their presence. Amna Nawaz talks to Refugees International's Dan Sullivan about genocide and the hostile conditions in Myanmar preventing Rohingya from returning home.

The Mueller report continues to make headlines in Washington, as some Democrats talk impeachment and battle the Trump administration over additional investigations and subpoenas, but how prominent is the subject among voters outside D.C.? Judy Woodruff talks to Chris Buskirk of American Greatness and Kent State University’s Connie Schultz about reactions to the report and election security fears.

Amid the ongoing opioid epidemic, drug manufacturers, doctors and pharmacists have all come under fire. But it's a drug distributor, a company called RDC, at the center of a new federal criminal case that equates its business operations with illegal drug trafficking. William Brangham talks to The Washington Post’s Lenny Bernstein about whether the new charges could change the opioid business.

For decades, the Boy Scouts of America maintained a confidential blacklist of staff and volunteers accused of sexual abuse. The magnitude of that list, known internally as the perversion files, is only now being realized. John Yang talks to Jeff Anderson, an attorney who represents abuse survivors, about the “grossly deficient” response from the Boy Scouts and why the files should be made public.

Antarctica is virtually uninhabited by people. There are no roads, no cities, no government. But thanks to a remarkable Cold War diplomatic breakthrough, the last continent ever discovered remains a place devoted almost exclusively to science. William Brangham reports on how humans first found Antarctica, and how it proves that occasionally, even rivals can become partners.

The death toll from Sri Lanka's Easter massacre has risen to 321, as the country observed a national day of mourning Tuesday. Although the Islamic State made an unconfirmed claim of responsibility for the bombings, officials in Colombo blamed a local group and suggested the attacks might have been retaliation for the recent mass killing of Muslims in New Zealand. ITN's Debi Edward reports.

In our news wrap Tuesday, Saudi Arabia beheaded 37 people in the Kingdom’s largest mass execution since 2016.

Counting the roughly 327 million people currently living in the U.S. is a massive effort. And this year, before the next census moves forward, the Supreme Court must decide whether the Trump administration should be allowed to add a citizenship question to it, over the concerns of census experts. Judy Woodruff talks to the National Law Journal’s Marcia Coyle and NPR’s Hansi Lo Wang for analysis.

Nearly half of the Mueller report focuses on whether President Trump obstructed justice. Though it does not reach a definitive conclusion, it makes clear that Trump was sometimes protected by his advisers’ unwillingness to yield to his demands. Yamiche Alcindor talks to The Washington Post's Carol Leonnig about who in the president’s orbit pushed back and the pressure they felt when they did.

Democrats in the House and on the 2020 campaign trail are divided on whether to initiate impeachment proceedings against President Trump. While many feel his actions warrant impeachment, there is concern that public sentiment wouldn't support it. But Rep. Jared Huffman, D-Calif., thinks refraining from impeachment would violate a fundamental responsibility of Congress, as he tells Judy Woodruff.
