U.S. inflation cooled last month as the cost of gas, clothes, and used cars fell, providing some relief to consumers, while underlying price pressures also slowed more than expected. Excluding the food and energy categories, core prices were unchanged from May to June, a positive sign that higher gas prices haven't spread through the economy. Yet oil prices rose for a second day Tuesday as the United States renewed attacks on Iran and President Donald Trump announced a new blockade in the Strait of Hormuz. The increase threatens to undo at least some of the progress that occurred last month.
