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 part three, the Jan. 6 Select Committee examines the pressures mounting on the Justice Department and then-Vice President Mike Pence to intervene on Trump’s behalf. Georgia Secretary of State Brad Raffensperger recalls a phone call in which the former president tells him, “I just want to find 11,780 votes” — the number of votes needed to win the 2020 presidential election in the state. And the former president sends a now-famous tweet inviting supporters to Washington D.C. on Jan. 6, 2021, to protest the results of the 2020 election, saying it “will be wild.”

Tune in next week for the fourth and final installment of the audio-only version of the documentary here on The FRONTLINE Dispatch. Watch Democracy on Trial in full on FRONTLINE’s website, YouTube or the PBS App.
