WASHINGTON (AP) — U.S. consumers slowed their spending by 0.2% in December, cutting back for a second straight month in a worrisome sign for an economy struggling under the weight of a still out-of-control pandemic. The decline reported Friday by the Commerce Department followed a seasonally adjusted 0.7% drop in November. It was the latest sign that consumers, whose spending is the primary driver of the U.S. economy, are hunkered down and avoiding traveling, shopping and dining out. Since making a brief bounce-back from the viral pandemic last spring, consumer spending has barely grown. Sales at retailers have declined for three straight months.
