Welcome Back, Doctor Catcher Adler

The US President wraps up his trip to Europe, but is he taking the lead on Ukraine?

The BBC’s North America editor, Sarah Smith, who has been travelling with the US Commander-in-Chief on Air Force One, and Europe Editor, Katya Adler, drop by to chew over the transatlantic approach to the crisis.

Also… amid a growing feeling of global instability, Adam speaks to historian, philosopher, and best-selling author of 'Sapiens', Yuval Noah Harari, about the consequences – some unintended and overlooked – of the conflict in Ukraine.

Today’s Newscast was made by Tim Walklate, with Chris Flynn and Ben Cooper. The studio director was Hannah Montgomery. The editor was Jonathan Aspinwall.
