"I am your warrior. I am your justice. And for those who have been wronged and betrayed, I am your retribution." There has never been a US president like Donald Trump, and now he's back, this time with a detailed plan for his second coming. Ahead of the US election in November, Four Corners reporter Mark Willacy travels to Washington for a special two-part series.

Part two explores the key issues in the battleground states, travelling to the frontline of the immigration crisis in Arizona’s wild southern desert, as well as an abortion clinic which sees protestors gather almost daily. In Georgia, political fractures have opened in Black communities that were once a largely united voice. Meanwhile, inside the Trump juggernaut, fans are steadfast in their belief that he will make America great again.
