According to police statistics. There have been at least 354 murders this year, compared to 264 at the same time last year.
But the crime rate is far below that of the 1990s, when more than 2,000 people were killed in a single year. Shootings also increased in other major cities, including Chicago, Houston, Atlanta and Denver.
Mr. de Blasio and police chiefs have blamed the rise in violence in the city in part on the economic devastation of the pandemic, the release of thousands of people from prison and slowdowns in the criminal justice system.
The mayor said Thursday that his city was making a heroic comeback from the pandemic and that Mr. Trump was wrong to try to hurt his own hometown.
“The only anarchy in this country comes from the White House,” de Blasio told reporters.
Seattle and Portland could also face “devastating” budget cuts, according to the lawsuit. Seattle expects more than $230 million in federal grants for the fiscal year and Portland $340 million.
Seattle Mayor Jenny A. Durkan said she was confident the courts would side with the cities.
“It is immoral, unconstitutional and shameful that we are forced to spend resources on this political theater,” she said.
On Thursday, Governor Andrew M. Cuomo of New York, a Democrat who has fallen out with Mr. Trump, echoed the city’s argument that the federal designation was unconstitutional.
“Again, Mr. President, read the Constitution,” he said.
