Watch: Vance's mic muted over Springfield migrant claim

During the debate, Republican vice-presidential candidate JD Vance was fact-checked over his claims about Haitian migrants in Springfield, Ohio, who he and Trump have baselessly accused of eating their neighbours' pets.

Vance continued to speak - but his microphone was muted.
