  • Twenty-five years after the September 11 attacks, the United States continues to grapple with the wars, fear and political upheaval that followed. In "Toward the Turning," psychotherapist Scott Gibbs examines 9/11 as part of a destructive cycle of grievance, violence and retaliation between Islamist movements and Western powers. He argues that humanity must learn to coexist across profound cultural differences to escape this cycle of conflict.
  • Polling shows President Donald Trump is unpopular with independent voters — and the midterm elections could be a blue wave. But could Trump try to interfere with the election? He's used executive orders to attack voter eligibility, mail voting, voter databases and redistricting. How vulnerable are the midterms? How can we protect democracy?
  • Governor Greg Abbott is calling for the San Antonio electricity market to be opened up to private for-profit power companies. CPS Energy is the largest municipally owned electricity provider in the nation, and each year contributes about half a billion dollars to the city’s general fund. CPS Energy joins us to explain what Abbott’s proposal could mean for your power bill and for funding city programs.
  • San Antonio Councilwoman Marina Alderete Gavito is calling for renewed scrutiny of cybersecurity protections at the city’s municipally owned water and electric utilities following attacks on water systems in Minnesota.
  • Texas history is more than just history. It’s filled with myth— and amnesia—that provides a permission structure which fuels conservative politics. It also has a powerful influence on the nation as a whole.
