Donald Trump and Kamala Harris have faced off in what could be the final debate before the election in November.

The polls are neck and neck, both at the national level and in key swing states – and almost everyone likely to cast a vote in the US already has a strong opinion about Donald Trump.

But plenty of people were still making up their mind on Kamala Harris, so the pressure was on her to define herself and convince undecided voters.
