FRONTLINE investigates the roots of the federal criminal case against former President Donald Trump stemming from his 2020 election loss in a special audio version of the new documentary Democracy on Trial.

In this final installment, the Jan. 6 Select Committee examines what happened inside the White House on Jan. 6, 2021. What was former President Donald Trump doing for 187 minutes during the violent insurrection at the U.S. Capitol, when some in the crowd were chanting, “Hang Mike Pence”? What did Cassidy Hutchinson, a former top aide to then-President Donald Trump’s Chief of Staff Mark Meadows, testify that she witnessed that day? Plus: As a potential criminal trial looms, how will it differ from the Jan. 6 Select Committee’s hearings? And what are the trial’s implications for democracy?
