The white supremacist who shot 10 people dead in Buffalo, New York, was able to buy an assault rifle months after New York state police took him into custody for making a threat about committing violence. The gun store owner who sold the weapon says a background check showed a clean record. We look at how background checks alone are not enough to prevent gun violence, as both mass shootings and weapons sales have skyrocketed in recent years without more legislation at the federal level.

As the United Nations warns about the devastating global impact of Russia’s invasion of Ukraine, talks to negotiate a peace settlement appear to have collapsed. Russian President Vladimir Putin appears determined to push forward despite a more resilient Ukrainian defense than expected, as both sides seem to be fixated on gaining military and territorial victories. Meanwhile, the U.S. continues to pour millions of dollars in weapons into Ukraine.

House lawmakers have raised alarm over a nationwide baby formula shortage after a manufacturer in Michigan shut down over health concerns and was linked to the deaths of two infants. Advocates are calling for greater accountability and investigation into the manufacturer, Abbott Laboratories, even as the Food and Drug Administration is in talks to allow the plant to reopen.

In a rare interview from the frontlines of the Russian invasion, we speak with American journalist Billy Nessen in the Ukrainian city of Severodonetsk. It is the easternmost city still held by Ukrainian forces after almost three months of war. He says Russian troops have devastated the city with heavy shelling. The interview with Nessen was interrupted when a shell landed in the building next door. Nessen speaks about the Ukrainian resistance, the Azov Battalion and more, including the U.S.

We look at the Democratic Party’s opposition to progressive challengers such as Nina Turner, former Ohio state senator who earlier this month lost her congressional primary challenge after facing massive spending and attacks by super PACs. Turner says the corporate wing of the Democratic Party seeks to consolidate the existing leadership’s power while shutting down champions of progressive policies like Medicare for All.

We look at Tuesday’s primary elections across five states, which could set the tone for this year’s midterm elections in November. Progressives won in some primary elections despite opposition from within the Democratic Party, as well as deep-pocketed outside groups. “What you’ve seen is a surprising backlash at the voter level to all of the money that flooded in,” says investigative journalist David Sirota of The Lever.
