ARTS: Robert Therrien: A giant in the world of giant art
Robert Therrien (1947-2019) arrived on the emerging Los Angeles art scene in the early 1970s and became best known for his oversized objects—tables, chairs, and household accessories that dwarf the viewer. He is now the subject of a larger-than-life exhibition at the Broad in Los Angeles, called “Robert Therrien: This Is a Story.” Luke Burbank takes the measure of a giant of the art world.

United States: Signs of the Times: Removing the Stories of America’s Past from Our National Parks
Signs informing visitors about the country’s past are a key part of our national parks and historic sites. But following an executive order from President Trump, the Interior Department removed dozens of signs that the administration says promote “divisive narratives” and “corrosive ideology” — information on topics including race relations, slavery, women’s history, indigenous peoples and climate change. Hundreds of other signs, books and brochures were flagged for review. Jim Axelrod examines efforts to suppress the lessons of America’s complicated past.

BOOKS: Hail Caesar! How Sid Caesar reinvented comedy for television
Comic Sid Caesar (1922-2014) was a master of humor, slapstick and accents, whose 1950s series “Your Show of Shows” and “Caesar’s Hour” rewrote the rules of comedy in the new medium of television. Correspondent Mo Rocca speaks with David Margolick, author of the biography “When Caesar Was King,” and comedian Robert Klein, about the unique gifts of Caesar (whose reputation was overshadowed by the writers he hired, including Mel Brooks, Carl Reiner, Larry Gelbart, Woody Allen and Neil Simon); and how the hard work of seemingly effortless laughs took its toll on the comedian.

COMMENT: Why it’s worth being bored
Resolving boredom through our incessant focus on our devices has also, according to New York Times bestselling author Arthur Brooks, ended our willingness to let our minds wander — inhibiting abstract thought and making us vulnerable to anxiety and depression. He talks about his new book, “The Meaning of Your Life: Finding Purpose in the Age of Emptiness,” and why constant distraction hinders our ability to be fully alive.

SUNDAY PROFILE: Cory Booker: “We the People Are the Heroes This Country Needs”
New Jersey Sen. Cory Booker has been one of the faces of the Democratic Party’s resistance to the Trump administration — from a record filibuster criticizing the president’s policies to calls for accountability over U.S. involvement in the war with Iran. He also expresses his hopes for our nation in a new book, “Stand,” in which he encourages Americans to unite, reminding us of our common virtues. He talks with Faith Salie about a political career forged in Newark, New Jersey (“the toughest place in politics ever”), and how it’s time to “seize, reclaim, and redeem America’s dream.”
