Joe Biden to visit Uvalde, Texas

Ahead of Joe Biden's visit, we are in the small Texas town of Uvalde, scene of the latest American mass shooting.

We are also in Severodonetsk, as Russian forces try to take control of the eastern Ukrainian city.

Plus, building an entire school using 3D printing... we'll show you how...

Joining Paul Henley to discuss these and other issues are Verashni Pillay, a South African journalist and founder of the Explain news portal; and Phillips Payson O'Brien, an American historian and professor of strategic studies at the University of St Andrews in Scotland.
