An emotional Tim Walz issued a rallying cry for Democrats as he accepted the vice-presidential nomination. "We’ll sleep when we’re dead. And we’re gonna leave it all on the field," he told the party convention

'That’s my dad': Tim Walz's son's tearful reaction to speech
Image source, EPANow Walz is discussing Kamala Harris's agenda and what he says she wants to do for the country.
"No matter who you are, Kamala Harris is gonna stand up and fight for your freedom to live the life you want to lead."
Walz is hitting JD Vance, saying he "doesn't know how to be a good neighbour".
Republicans plans for a second Trump term is "an agenda that serves nobody but the richest people and the most extreme voices in our country. An agenda that does nothing for our neighbours in need".
He begins a chant of "we're not going back" around the arena - a slogan the campaign has adopted in recent weeks.
Walz says he wants Americans to have the freedom "to make a better life for yourself and the people you love" and "make your own health care decisions".
He says people shouldn't have to worry about their kids getting "shot dead in the halls" of school, which he says is different from the kinds of freedoms Republicans want to champion.
Walz is now talking about women's health and fertility, saying the issue of IVF treatments are personal for he and his wife Gwen Walz.
The topic has become somewhat awkward for the Harris-Walz campaign in recent days, as he has faced accusations of misleading voters about his family's reliance on fertility treatments to have their children.
Their family received a different kind of fertility treatment, Gwen Walz recently clarified, not IVF.
"I’m letting you in on how we started our family because that’s a big part of what this election is about -freedom," Walz said.
Walz moves on to talk about his time as governor as Minnesota, an office to which he was first elected in 2018.
He touts his policy record, including free school lunch for all students in the state.
Talking about reproductive freedoms, he says, "in Minnesota, we respect our neighbours and the personal choices they make".
He repeats a line he's already said on the campaign trail several times: "Mind your own damn business", even when you don't agree with other people.

"They saw in me what I hoped to instill in them - a commitment to the common good. An understanding that we’re all in this together," he says.
"I learned an awful lot" in Congress, Walz adds, including compromising with colleagues who didn't agree with him.

"Growing up in a small town (with 400 people), you learn to take care of each other."
He also talked about his time in the Army National Guard and how he used the GI Bill to pay for his college education before becoming a high school history teacher and football coach.
Walz's military record has come under scrutiny since he became Harris's running mate. He's faced questions about the timing of his retirement from the National Guard before his unit was sent to Iraq.
Tim Walz begins by thanking Kamala Harris "for putting your trust in me and for inviting me to be part of this incredible campaign".
He also thanks President Joe Biden.
"It is the honour of my life to accept your nomination for vice-president of the United States."

Image source, Reuters/GettyWith Tim Walz speaking shortly, let's take a look at the two potential vice-presidents.
The running mates will face off in a vice-presidential debate on 1 October in New York City. Democratic Governor Tim Walz was the first to agree to the date, with Republican Senator JD Vance following suit.
It will be moderated by the BBC’s US partner, CBS News. Both men have come under fire in recent weeks as the campaign heats up ahead of the November election.
Vance has criticised Walz’s military service, accusing him of “stolen valour”. And Donald Trump's vice-presidential candidate has had to defend comments in which he said those without children are not invested in the future of the country and called Democratic politicians a "bunch of childless cat ladies with miserable lives".
Another thing we will be keeping an eye on at the debate is the word “weird”. Walz rose up Kamala Harris’s VP shortlist after he started branding Donald Trump and Vance as “weird”.
The line proved effective for Democrats and seems to have got under the skin of Vance and Trump.
Image source, ReutersWe're being reminded of Tim Walz's career as a high-school teacher and sport coach.
Ben Ingman, one of his former pupils, tells a few stories about Walz and his wife before a squad of Tim Walz's former high school American football players, wearing mismatched jerseys, marches out on stage.
On the big screen, we're now seeing an autobiographical video about his upbringing in Nebraska, narrated by his wife.
Minnesota Senator Amy Klobuchar is now on stage singing Tim Walz's praises, saying the state "trusts" him.
"We love a dad in flab," she says, a joke that appears to fall a bit flat with the crowd.
She now recounts her own family's relationship with Walz, who she says "looks out for his neighbours" and applauds his military service record.
Walz, she adds, has "Midwestern common sense" and knows "how to school the likes of JD Vance".

The night is already well behind schedule, but now that John Legend’s on the stage, the crowd doesn’t seem to mind.
Volunteers are dancing in the aisles of the arena while delegates are standing up in their seats clapping along.
Legend, an outspoken critic of Trump, has hosted several concerts benefiting Democratic candidates in the past.

He's playing cover songs by Prince tonight as an ode to Tim Walz's roots in Minnesota.
Buttigieg responds to Vance comments on childless people
The crowd was quieter for much of Secretary Buttigieg’s speech, but at the end, when he turns to voting against “a politics of darkness” that he says the Trump team has been promoting, the thousands in the arena yell so loudly that we cannot hear the last lines of his speech.
We're now watching a video featuring veterans who have known Tim Walz, who are discussing how he helped them.
One of those featured was in his unit.
Echoing language we've heard several times previously at the DNC, Buttigieg says that Republicans believe that "everyone different from you is a threat".
"I believe in a different kind of politics," he says. "The kind of politics that Kamala Harris and Tim Walz are offering. That kind of politics just feels better."
Buttigieg is also recounting his own unlikely career in politics, and a family he says was "impossible" as recently as 25 years ago.
"This kind of life went from impossible....to almost ordinary, in less than half a lifetime," he says. "That didn't just happen. It was brought about through idealism and courage."
Some politics, he says, can make "an impossible dream" into a reality.
Image source, ReutersTransportation Secretary Pete Buttigieg - who is also known as Mayor Pete from his time leading the city of South Bend, Indiana - has a reputation for appearing on conservative US network Fox News and arguing for Democratic policies.
He has taken the stage at the United Center just now, repeating many of the same talking points now that he often goes to on Fox - hitting out on Donald Trump and his running mate JD Vance.
Republicans are about "grievance" and "darkness" he alleges.
Americans want more than darkness, he says, saying politics can even be "uplifting".

Tracy Prince and Kathy Sykes jumped out of their seats when they saw Oprah, who is from their home state of Mississippi, take the stage.
“We love Oprah so much,” Sykes says. “Everyone in Mississippi is so proud that she claims us.”
Sykes says Oprah’s speech was a “powerful message” to independent voters, in particular to vote for Harris.
“She gave very good reasons why - to choose common sense over nonsense,” Sykes says.
With just "75 days and a wake-up" before the November election, Maryland Governor Wes Moore says it's time to "get to work".
It's a message we've heard over and over again at this DNC, including from the Obamas yesterday.
Democrats here know that the Harris-Walz campaign is on an accelerated timeline, meaning that they must mobilise quickly to energise and organise voters.

Pete Buttigieg, who is set to speak shortly, is the Democrats’ star communicator of this younger generation.
I’ll be interested to see if he shows any inkling of regret that his name isn’t on the ticket, given that he ran for president in 2020 and was also recently under consideration to be Kamala Harris’s vice-president.
