On today's podcast:
1) US negotiators offered more significant security guarantees to Kyiv as part of President Trump’s renewed push to end the Russia-Ukraine war, but the effort still appeared part of a bid to pressure President Volodymyr Zelenskiy on territory. The Trump administration offered to provide Ukraine with strong “Article 5-like” security guarantees — a reference to NATO’s mutual defense clause — as part of the current deal to find a diplomatic solution to the conflict, a US official told reporters, without providing any details. Later on Monday, Trump said a negotiated end to the war was “closer than” ever and that the US was working with Europe on security guarantees. But then he appeared to suggest Ukraine ought to give up land as part of the deal. 
2) Nick Reiner, 32, was arrested and booked for the murder of his parents, the Hollywood director and actor Rob Reiner and photographer Michele Singer Reiner. The son was being held in jail in Los Angeles on no bail, the Los Angeles Police Department said in a statement on X. The case will be presented to the Los Angeles County District Attorney for filing consideration on Tuesday. Reiner, who directed 1980s classics like The Princess Bride and This Is Spinal Tap, was found dead Sunday at his home with his wife, both of whom appeared to have died from stab wounds, NBC News and other outlets reported, citing a source close to the family.
3) Shock over a shooting rampage at Brown University over the weekend is giving way to frustration over the lack of video footage and suspects. Authorities in Providence, Rhode Island, said Monday they hadn’t identified any new persons of interest in the shooting that killed two people and injured nine on the Ivy League campus Saturday afternoon. A person detained earlier was released late Sunday, and officials have said a lack of clear security-camera footage from inside the Barus & Holley engineering building where the shooting took place has slowed the search.
