Congressional hearings into the January 6 attack on the U.S. Capitol have concluded for the summer after weeks of testimony. Among the key witnesses to appear before the committee was J. Michael Luttig, a former federal judge and renowned conservative legal scholar.

On this special edition of The FRONTLINE Dispatch, listen to excerpts from an extensive interview with Luttig, as well as with U.S. Rep. Adam Kinzinger (R-Ill.), one of only two Republicans on the House select committee investigating January 6.

The interviews with J. Michael Luttig and Rep. Adam Kinzinger are available online in full as part of FRONTLINE's Transparency Project.

These interviews were conducted by producer Mike Wiser and the Kirk Documentary Group for FRONTLINE’s upcoming documentary Lies, Politics, and Democracy.
