"These are not acts of peaceful protest but, really, domestic terror," said Trump. And he condemned Democratic officials for not immediately accepting his offer of federal enforcement assistance, claiming, "They just don't want us to come."
The city has been the scene of protests since the August 23 shooting of Blake, who was hit seven times in the back by police as he tried to get into a car while they were trying to arrest him. Protests have been concentrated in a small area of Kenosha.
While there were more than 30 fires set in the first three nights, the situation has calmed since then.
Trump's motorcade passed throngs of demonstrators, some holding American flags in support of the President, others jeering while carrying signs that read Black Lives Matter.
A massive police presence, complete with several armoured vehicles, secured the area, and barricades were set up along several of the city's major thoroughfares to keep onlookers at a distance from the passing presidential vehicles.
Offering federal resources to help rebuild the city, Trump toured a high school that had been transformed into a law enforcement command post. He said he tried to call Blake's mother but opted against it after the family asked that a lawyer listen in.
He later added he felt "terribly" for anyone who suffered a loss, but otherwise only noted that the situation was "complicated" and "under investigation." The only words acknowledging the suffering of African Americans came from a pastor who attended the law enforcement roundtable.
Pressed by reporters, Trump repeatedly pivoted away from assessing any sort of structural racism in the nation or its police departments, instead blasting what he saw as anti-police rhetoric.
Painting a dark portrait of parts of the nation he leads, the President predicted that chaos would descend on cities across America if voters elect Democrat Joe Biden to replace him in November.
Biden hit back, speaking to donors on a fundraising call after Trump left Kenosha.
"Donald Trump has failed to protect America. So now he's trying to scare the hell out of America," Biden said. "Violence isn't a problem in Donald Trump's eyes. It's a political strategy."
The election is playing out in "anxious times," with "multiple crises," Biden said. He included police violence in the list, along with the coronavirus pandemic and its economic fallout, and said Trump refuses to address any of them honestly.
Trump aides believe that his tough-on-crime stance will help him with voters and that the more the national discourse is about anything other than the coronavirus, the better it is for the President.
Biden said after Trump's Wisconsin visit, "The vast majority of cops are honourable, decent and real. But the idea that he wouldn't even acknowledge the problem – and white nationalists are raising their heads all across the country."
Trump condemned unrest in Portland, Oregon, too, where a supporter was shot and killed recently — and an increase in shootings in cities including Chicago and New York — and tried to take credit for stopping the violence in Kenosha with the National Guard.
But it was Wisconsin's Democratic Governor, Tony Evers, who deployed the Guard to quell demonstrations in response to the Blake shooting, and he had pleaded with Trump to stay away for fear of straining tensions further.
"I am concerned your presence will only hinder our healing," Evers wrote in a letter to Trump. "I am concerned your presence will only delay our work to overcome division and move forward together."
Biden has assailed Trump as an instigator of the deadly protests that have sprung up on his watch. On the eve of his visit, Trump defended a teenager accused of fatally shooting two men at a demonstration in Kenosha last week though he did not mention the young man today.
Claiming the mantle of the "law and order" Republican candidate, Trump insists that he, not Biden, is the leader best positioned to keep Americans safe. He said his appearance in Kenosha would "increase enthusiasm" in Wisconsin, perhaps the most hotly contested battleground state in the presidential race.
Blake's family held a "community celebration" at a distance from Trump's visit.
"We don't need more pain and division from a president set on advancing his campaign at the expense of our city," Justin Blake, an uncle, said in a statement. "We need justice and relief for our vibrant community."
The NAACP said neither candidate should visit the Wisconsin city as tension simmers.
Biden's team has considered a visit to Kenosha and had previously indicated that a trip to Wisconsin was imminent but has not offered details.
Protests in Kenosha began on the night of Blake's shooting, August 23 and were concentrated in the blocks around the county courthouse downtown. There was an estimated US$2 million in damage to city property, and Kenosha's mayor has said he is seeking US$30 million from the state to help rebuild.
The violence reached its peak the night of August 25, when police said the 17-year-old armed with an illegal semi-automatic rifle shot and killed two protesters in the streets.
Since then marches organised both by backers of police and Blake's family have all been peaceful with no vandalism or destruction to public property.
