CBS News Sunday Morning Lineup Revealed for March 22 Broadcast

Martha Stewart spent part of her Sunday morning competing to spot and identify plant and animal species alongside CBS News technology correspondent David Pogue, joining him in what the iNaturalist app calls a "bioblitz" — a timed competition with other users to spot and ID species. The segment anchored the March 22 broadcast of the Emmy Award-winning CBS News Sunday Morning, hosted by Jane Pauley and produced by executive producer Rand Morrison, which aired from 9:00 to 10:30 a.m. ET on CBS.

The iNaturalist cover story framed the free cellphone app not merely as a nature identification tool but as a data pipeline for scientists studying biodiversity, species decline, and habitat loss. Pogue's segment with Stewart put the app's social and competitive features on display alongside its scientific value.

Faith Salie sat down with New Jersey Senator Cory Booker for the Sunday Profile, drawing on a political career Booker described as forged in Newark, which he called "the toughest place in politics ever." Booker, who has been a prominent face of Democratic resistance to the Trump administration through a record-breaking filibuster and calls for accountability over U.S. involvement in the war with Iran, told Salie it is time to "seize, reclaim, and redeem the dream of America." His new book, "Stand," encourages Americans to stand together by reminding them of shared virtues.

Jim Axelrod traveled to Muir Woods in California and the President's House in Philadelphia to examine the removal of interpretive signs from national parks and historic sites. Following an executive order from President Trump, the Department of the Interior removed dozens of signs the administration claims promote "divisive narratives" and "corrosive ideology," covering topics including race relations, slavery, women's history, Indigenous peoples, and climate change. Hundreds more signs, books, and pamphlets have been flagged for review.

Tracy Smith interviewed Lisa Kudrow about the return of her HBO series "The Comeback," which is making a comeback for the third time. Luke Burbank headed to The Broad Museum in Los Angeles for a retrospective on the late artist Robert Therrien, perhaps best known for his large-scale objects. Mo Rocca examined the life and legacy of 1950s television star Sid Caesar, pegged to David Margolick's new book "When Caesar Was King: How Sid Caesar Reinvented American Comedy."

Seth Doane spoke with chef Ruthie Rogers about The River Café in London and her new book "Ruthie's Table 4," in which she reminisces with famous friends about food. National security correspondent David Martin reported on the latest developments from the war with Iran, a separate thread from Booker's political commentary on the same conflict. CBS News contributor Arthur Brooks offered his thoughts on the meaning of life in the opinion segment.

Full episodes streamed on the CBS News app beginning at 11:00 a.m. ET and remain available on demand through CBSNews.com, CBS.com, and Paramount+, accessible on Apple TV, Android TV, Roku, Chromecast, Amazon Fire TV, and Xbox.
