Trump has left US ‘in tatters’, Biden and Harris say

Democratic presidential candidate Joe Biden and running mate, Kamala Harris, have attacked President Donald Trump as an incompetent leader who has left the US in tatters.

The pair held their first campaign event together, a day after Mr Biden unveiled Ms Harris as his number two.

President Trump hit back, saying Ms Harris had dropped like a rock in her own presidential bid.

Mr Biden will face Mr Trump, a republican, in November’s election.
