Kamala Harris to give first big interview as nominee in key test of credibility

Democratic presidential candidate will sit down with running mate Tim Walz and CNN's Dana Bash on Thursday

Kamala Harris on Thursday will give her first major interview since becoming the Democratic presidential nominee in what is being seen as a key test of her credibility after a prolonged honeymoon that has seen her surge ahead of Donald Trump in opinion polls.

She and her running mate, Tim Walz, will face CNN's Dana Bash in a pre-recorded event that was scheduled following some criticism of Harris's reluctance to expose herself to media scrutiny following her ascent to the top of the Democratic ticket last month in place of Joe Biden, who withdrew from the race on 21 July.
