The U.S. economy grew a little more slowly than first thought during April, May, and June.
Wednesday's update of gross domestic product growth in the second quarter shows the economy expanding at a healthy 3.3 percent.

Higher energy costs can hurt the economy by leaving consumers and businesses with less money to spend on other goods.
