Air pollution has become severe in the eastern United States due to smoke from wildfires in Canada. President Trump of the United States argued that Canada is not properly managing its forests and that the US is suffering damage, claiming that additional tariffs should be imposed on Canada. President Trump criticized Canada for its fault, saying that it causes billions of dollars in losses to the US every year due to recurring problems. However, the imposition of tariffs under the 'International Emergency Economic Powers Act' previously used by President Trump has been blocked by a federal court ruling. Air quality in the eastern United States, including New York City, is improving in the afternoon.
