On the first day of early voting in Detroit, Michigan, rapper Lizzo campaigned for Kamala Harris, saying she rejected the argument that America was not ready for a female president, adding, “It’s about damn time”. In Atlanta, Georgia, Harris was joined by singer Usher, with the Democratic candidate describing Donald Trump’s speeches as “nonsense”.

With Harris and Trump essentially tied in the most competitive states, both campaigns are focused on early by mail or in person voting, with just 17 days until the 5 November election.

In the battleground of Pennsylvania, Trump escalated his personal attacks on Harris, calling her a “shit vice-president”. The Republican candidate had billed the event as the start of his final argument to voters but quickly went off script with a long story about Arnold Palmer that included remarks about the genitalia of the late golfing legend.

Here’s what else happened on Saturday:

Kamala Harris election news and updates

• In both Detroit and Atlanta, Harris urged her supporters to put in an all-out effort to win. “On election day, we don’t want to have any regrets about what we could have done these next 17 days,” she said. Harris hammered Trump for a second straight day for cancelling events and for avoiding another presidential debate because of what she called “exhaustion”. Her campaign called Trump’s Pennsylvania rally “junk”, saying he had focused on the issue “most important to voters in this election: a deceased golfer’s ‘anatomy’.”

• In Atlanta, Harris said Trump was “cruel” for how he talked about the grieving family of a Georgia mother who died after complications from an abortion pill. Harris blamed Amber Thurman’s death on Georgia’s abortion restrictions and referenced a clip of Trump at a Fox News town hall. When asked about the Thurman family joining a separate media call, Trump reportedly said “we’ll get better ratings, I promise.” “Donald Trump still refuses to take accountability, to take any accountability, for the pain and the suffering he has caused,” Harris said.

• Harris repeated her call for a ceasefire in Israel’s war in Gaza and said it was important to seize the opportunity provided by the killing of Hamas leader Yahya Sinwar. Harris dodged a question on whether Arab American and Muslim anger over US support for Israel could cost her the election in the battleground state of Michigan, but said she would continue speaking out about the tragic loss of innocent lives. “I speak publicly all the time about the fact that there are so many tragic stories coming from Gaza,” Harris said.

Donald Trump election news and updates

• In Latrobe, Pennsylvania, Trump said Harris is further to the left than Democratic Senators Elizabeth Warren and Bernie Sanders, adding “You have to tell Kamala Harris that you’ve had enough, that you just can’t take it any more.” Trump underscored the importance of the eastern state’s electoral college delegates to the overall election: “If we win Pennsylvania, we win the whole damn thing.”

• Donald Trump’s campaign may be failing to reach thousands of voters they hope to turn out in Arizona and Nevada, with roughly a quarter of door-knocks done by America Pac flagged by its canvassing app as potentially fraudulent, according to leaked data and people familiar with the matter. The Trump campaign earlier this year outsourced the bulk of its ground game to America Pac, the political action committee founded by Elon Musk, betting that spending millions to turn out Trump supporters, especially those who don’t typically vote, would boost returns.

Elsewhere on the campaign trail

• Billionaire Mark Cuban – who has emerged as an energetic campaign surrogate for Harris – has told the Guardian that Trump’s planned tariffs could put “small retailers and manufacturers out of business.” “Small businesses don’t have the pricing elasticity of larger companies. They can’t pass on the incremental and administrative costs associated with tariffs.”

• Elsewhere another billionaire – Elon Musk – campaigned for Trump in Pennsylvania. Speaking in Harrisburg, he announced he would start randomly distribute cash awards – $1m each day until the election – to a registered voter in the state who signed his organisation’s petition. The Tesla and SpaceX CEO has taken an increasingly visible role in Trump’s campaign and has donated almost $75m to his political organisation America PAC.
