Before making price adjustments, spending was flat. That was just b elow the median forecast in a Reuters poll of 0.1 percent i ncrease.
Pressure is rising on policymakers at the U.S. Federal Reserve to do more to help the sputtering U.S. economy. The faltering recovery also weighs on President Barack Obama's hopes of reelection in November.

Analysts had expected a gain of 0. 4 percent. After tax income climbed 0.3 percent in J une w hen accounting for higher prices.
With price-adjusted incomes rising in June and consumption f alling, the saving rate f or households rose to 4.4 percent, its highest level in a year.
A report on Friday is expected to show the jobless rate holding at 8.2 percent in July. It has been above 8 percent since February 2009 - nearly all of Obama's time in office so far.
On Tuesday, policymakers at the U.S. Federal Reserve were to start a two-day meeting where Fed Chairman Ben Bernanke has said they would be looking for signs of any stall in the recovery of the labor market.
No major policy announcement is expected although some economists think the Fed this week could push further into the future its conditional pledge to keep rates near zero through late 2014.
Inflation pressures appear to be muted.
