FRONTLINE went inside former President Trump’s high-stakes battle for control of the GOP, examining how he attacked fellow Republicans and used inflammatory rhetoric that rallied his base and further divided the country in his first year as president. Through interviews with longtime Republican legislators like former Sen. Jeff Flake (R-Ariz.), House Freedom Caucus members including Rep. Jim Jordan (R-Ohio), former senior White House officials including Kellyanne Conway and Sean Spicer and other D.C. insiders, “Trump’s Takeover” examined how, years before the Jan. 6., 2021 U.S. Capitol attack, the president was remaking the GOP in his own image, counter-punching when criticized and publicly attacking those who defied him.
