Democrats welcome choice of Minnesota governor to be Harris’s running mate in race against Donald Trump and JD Vance

• Who is Tim Walz?
• How could Walz’s political record help and hurt Harris?

As we await Kamala Harris’s running mate announcement, Americans in some states are heading to the polls today.

Voters in Kansas, Michigan, Missouri and Washington state will cast ballots in their congressional primaries today. Results in Michigan will be especially scrutinized, as the battleground state will play a key role in the presidential election.

The American Israel Public Affairs Committee (Aipac) pumped more than $8.5m into the race in Missouri’s first congressional district in support of Bush’s rival, St Louis prosecutor Wesley Bell, through its campaign funding arm, the United Democracy Project (UDP). …

The UDP accounts for more than half of all the money spent on the race outside of the campaigns themselves. Much of it comes from billionaires who fund hardline pro-Israel causes and Republicans in other races, including some who have given to Donald Trump’s campaign.

With the support of 99% of all participating delegates in the virtual roll call, Vice-President Harris has historic momentum at her back as we embark on the final steps in officially certifying her as our Party’s nominee.

We thank the thousands of delegates from all across the country who took seriously their responsibility throughout this process to make their voices – and the voices of their communities – heard.
