Rubio, Antifa and the global threat from the far-left

On Thursday in Washington DC Marco Rubio, the Secretary of State, will host an international summit on the threat posed by "the resurgence of transnational far-left terrorism.” There will be a particular focus on the loosely composed group the Trump administration calls Antifa.

What is this group? Is it a significant threat? Or is there something motivating the DC summit?

BBC journalist Mike Wendling joins us to discuss whether the Trump administration is right to worry about far-left groups like Antifa.
