Pittsburgh voters split ahead of US presidential debate

Residents in the US city of Pittsburgh, in the key presidential swing state of Pennsylvania, are split ahead of the first televised debate between Kamala Harris and Donald Trump.

The debate will take place in Philadelphia, also in Pennsylvania, with both candidates recognising how crucial the state's support is in securing the White House in November.

Much has been made of the candidates' different styles, with Trump under pressure to rein in his aggression and Harris needing to reach out to undecided voters with policy.
