The government reported today thatU.S.gross domestic product increased at a 1.3% annual rate in the first quarter, which is the weakest since the first quarter of 2003, following the recession of 2002. The report will be revised in each of the next two months, but it shows some worrisome trends. Home construction continued to decline and the trade deficit grew. Inflation gauges in the report surged to their highest since 1991.
