Donald Trump is set to be sworn in as President of the United States of America for the second time - but, from TikTok and the southern border, to Ukraine and the fragile ceasefire between Israel and Hamas in Gaza - he faces even bigger challenges than he did eight years ago.

Will he really end the Ukraine war on day one, pardon the January 6 rioters in the “first hour” and potentially bring back TikTok? And while his personal brand of right-wing populism is totally dominant now, will there be a progressive backlash or resistance?

In this week’s episode of the Fourcast, Matt Frei is joined by Channel 4 News's very own America experts - Siobhan Kennedy and Kiran Moodley.
