Harris campaign raised $540m amid surge during Democratic convention

Trump has also proved to be a formidable fundraiser but appears to be outpaced in Harris's month-old campaign

Kamala Harris's presidential campaign says it has now raised $540m for its election battle against Donald Trump.

The vice-president's campaign has had no problems getting supporters to open their wallets since Joe Biden announced on 21 July he was ending his run for re-election to the White House and quickly endorsed Harris. The campaign said it saw a surge of donations during last week's Democratic national convention in Chicago where Harris and her vice-presidential running mate, Minnesota governor Tim Walz, accepted their nominations.
