In “Lies, Politics and Democracy,” FRONTLINE examines how officials fed the public lies about the 2020 presidential election and embraced rhetoric that led to political violence.

An epic examination of former President Donald Trump’s influence on the Republican Party, the documentary presents startling details from GOP insiders on how the indulgence of Trump’s authoritarian impulses and embrace of his rhetoric enabled his power over the American political system, leading the nation to a precarious moment in which most Republican voters now believe the lie that the 2020 election was stolen.

Told in part through the perspectives of key Republican players and party leaders, the two-hour special provides first-person accounts from those who sounded the alarm about Trump, and those whose warnings were minimized or silenced all along the way.
