U.S. economic growth was lower than expected this spring with cautious businesses largely offsetting more robust consumer spending. Gross domestic product (GDP) grew at a seasonally adjusted annual rate of 1.2 percent in the second quarter, the Commerce Department said. The figure was well below the 2.6 percent growth economists expected. In the first quarter, GDP advanced at a downwardly revised 0.8 percent pace. The first quarter was previously seen as increasing 1.1% from the prior period.
