Speaking at a regional airport in Mosinee, a town of about 4500 people, the Republican presidential candidate warned that even allies like the European Union would face new trade restrictions if he wins the US election against Democratic nominee Kamala Harris.
He repeatedly presented migrants as a grave danger to Wisconsin, warning without evidence that immigrants in the country illegally could evict local residents from their homes.
"Crime is through the roof, and you haven't seen the migrant crime yet," Trump said. "It started, and it's vicious, but you haven't seen the extent of it yet."

Trump also warned, as he has in previous rallies, that the 2024 election could be the nation's last.
Support for the former president has eroded among most demographic groups over the summer when his Democratic rival, Vice President Kamala Harris, replaced President Joe Biden atop the Democratic ticket.
Nationally, Harris leads Trump among Hispanic voters by 13 percentage points, according to the latest Reuters/Ipsos poll, conducted in August; Biden led that demographic by just five points in May. Among Black Americans, she has been outperforming Biden by seven points.
But she has barely moved the needle among white voters, those same polls show. Whites without a college degree, long the linchpin of Trump's coalition, still favour him by 25 points, according to the latest Reuters/Ipsos poll. They favoured Trump by 29 points when he was running against Biden.
Several Trump advisers and allies have told Reuters in recent weeks that maintaining his margins and driving turnout among working-class whites will be crucial if he is to defeat Harris.
That is especially true in northern "Rust Belt" states including Wisconsin, which skew white and have large rural populations. Trump won the presidency in 2016 in part by winning these areas by promising to bring back industrial jobs to the region.
"We're not going to watch our wealth and our jobs get ripped away from us and sent to foreign countries, and Wisconsin will be one of the biggest beneficiaries," Trump said of his proposed trade policies.
Mosinee, where Trump spoke on Saturday, is near Wausau, a small city of about 40,000, but hours from the state's major population centres, Milwaukee and Madison.
While the Trump campaign has identified Hispanics and Black men as areas of growth for the Republican Party, much of Trump's campaigning in recent weeks has been in small Rust Belt cities and towns that have few of either demographic.

Trump's running mate, Ohio US Senator JD Vance, is expected to hit relatively rural areas of the Rust Belt hard in the final weeks before the election, two Trump advisers told Reuters.
The Saturday rally was one of the last public appearances Trump will make before his debate with Harris in Philadelphia on Tuesday. Many of his allies are pushing him to concentrate his attacks on policy and steer clear of deeply personal broadsides.
Trump did not concentrate on Harris' racial identity during his speech, which was laden with grievances, yet a recording the campaign played during the rally sounded like an imitation of Harris' laugh, which Trump has frequently derided.
Trump told the crowd he would purge the federal government, including public health and intelligence agencies, of corrupt actors.
He repeatedly attacked Fani Willis, the district attorney in Georgia who is prosecuting Trump for trying to overturn his 2020 defeat in that state to Biden.
Trump also said he would support modifying the 25th Amendment to the US Constitution to make a vice president covering up a president's mental incapacity an impeachable offence.
