Inflation rose slightly less than expected in April despite the arrival of President Donald Trump's sweeping international tariffs early in the month, according to a Bureau of Labor Statistics report on Tuesday.

Core CPI, which excludes volatile food and energy prices and is seen as a better measure of underlying inflation trends, was up 0.2% from March to April and 2.8% year over year. The monthly figure came in lower than the 0.2% gain expected by economists, while the annual increase matched forecasts.
