Brian O'Donovan's lively and authoritative reporting of a tumultuous period in American life has been must-watch TV. Four Years in the Cauldron is his account of four busy years working in the US. He draws a compelling picture, full of telling colour and detail, of covering its fractured politics, particularly the extraordinary presidency of Donald Trump and the knife-edge election of Joe Biden. And he gives his unique perspective on big stories such as the Covid emergency, the Capitol riot, the murder of George Floyd and trial and conviction of his police killer. Four Years in the Cauldron is a must-read for getting to grips with the US at a moment of profound reckoning.
