The State of Trump's Union is a 10-part series airing on The Last Word in the run-up to the US election in November.

We'll be talking to a variety of people with informed views about the issues dividing and uniting the United States, where the country is politically, socially and economically, the dangers it's facing, where power lies and how it is used.

Our next guest is actor Richard Schiff, star of the hugely popular US political drama The West Wing.

He joined Matt to discuss Joe Biden, the potential transition of power and how The West Wing's depiction of American politics compares to what the Trump administration is doing.
