How far should the government go to protect America?
1w ago00:33:30Summary readyThis September marks 25 years since terrorists hijacked planes and steered them into the twin towers of the World Trade Center. They steered a third plane into the Pentagon. A fourth was headed for the U.S. Capitol, but crashed into a field in Pennsylvania after its passengers overpowered their attackers.In the days — and years — that followed America’s leaders walked a fine and sometimes blurry line: how to prevent an attack like that from ever happening again?

As part of a conversation about the legacy of 9/11 at The Aspen Ideas Festival, host Mary Louise Kelly spoke with two of the country's leaders during that time: Alberto Gonzales, who was serving as White House counsel, and Jeh Johnson, who became Homeland Security Secretary under President Obama.Email the show at sourcesandmethods@npr.orgNPR+ supporters hear every episode without sponsor messages and unlock access to our complete archive.
