The stakes for Kamala Harris and Tim Walz were high as they sat down with CNN for their first interview since Joe Biden stepped aside. These were their biggest moments.

Here's what's happening next in US politics in the not-too-distant future.

The two presidential candidates will face off in a debate next month on September 11 at 11am AEST.

The debate will be hosted by ABC News (America) in Philadelphia, Pennsylvania — a key battleground state in the November election.

CNN's June debate between Biden and Trump had muted microphones when candidates were not speaking.

Earlier this week a Trump spokesperson said the two sides had agreed to the same terms, but a Harris spokesperson said conversations were still ongoing.

The third part of CNN's exclusive interview with Kamala Harris and Tim Walz, has been uploaded to the network's YouTube channel.

Jeremy Barr from the Washington Post just spoke to News Channel about how Kamala Harris and Tim Walz's interview has been received in the US.

"I think the consensus was that she didn't do incredibly well but she did well enough to not generate negative headlines about it," Barr says.

"The format was a little bit stilted, you had two people sitting at a table with the moderator across from them. It was a strange dynamic but she seemed to do fairly well, I think she hit most of her policy points.

"[CNN] were definitely tying to hold them accountable, push them on past inconsistencies.

"I think because this is the first interview they've done together the CNN anchor wanted to take advantage of that and push them."

CNN has uploaded the second part of its exclusive interview with Kamala Harris and Tim Walz to its YouTube channel.

Kamala Harris's decision to avoid interviews like this up until now meant there was plenty of anticipation - and pressure - on the vice-president in the lead up. 

Republicans have seized on some of the clunkier language that she has become known for, often referred to as "word salads".

And they're keen to highlight what Donald Trump has labelled her "flip-flops" on policy areas like fracking and immigration. 

Harris was on the defensive for quite a bit of the interview, trying to argue that while her positions had shifted, her values had not. 

She didn't seem totally at ease with the format, and interviewer Dana Bash had to follow up on what should have been an easy question about what she'd do on her first day in the White House. 

But there didn't appear to be any catastrophic stumbles, and Trump responded on social media with the message: "BORING!!!"

Harris's campaign will be hoping this hasn't done anything to halt her early momentum. 

But will it be enough to change the mind of anyone who's currently unsure about whether she should be elected to the top job? 

Either way, the pressure won't relent any time soon. The next big test could come when she faces off against Trump in their first debate next month. 

Since this was an exclusive interview with CNN, you could only watch the interview on the network's stations.

But it has since uploaded the first part of Kamala Harris and Tim Walz's interview to its YouTube channel.

CNN's interview with Democratic presidential nominee Kamala Harris and her running mate Tim Walz has wrapped up.

But don't go anywhere, as we'll still have plenty of analysis from our Washington DC bureau colleagues as we recap the key moments.

Tim Walz has been asked about the viral moment his son Gus was seen crying and shouting "that's my dad" at the Democratic National Convention, last week.

He says it was so important that his son feels that sense of pride for his dad.

"It was just such a visceral, emotional moment that I'm grateful I got to experience it," Walz says.

He then goes onto say how proud he is of his son, his daughter Hope, and his wife Gwen.

"I think the one thing is, talking about the era we're in is our politics can be better. It can be different," Walz says.

He says families can be involved in politics and these are the kinds of moments, people can be shown.

"I hope that there was a hope, people felt that out there, and I hope they hug their kids a little tighter, because you just never know, and life can be kind of hard."
