The U.S. economy grew at just a 0.7 percent annual rate in the first quarter of this year, according to the latest report on the gross domestic product from the Commerce Department. That's below market expectations and indicates the economy grew at the slowest pace in three years.

Weak auto sales and lower home-heating bills dragged down consumer spending, offsetting a pickup in investment led by housing and oil drilling. Employment costs rose 0.8 percent in the first quarter.

This "advance" estimate showed the U.S. economy with its slowest growth since the first quarter of 2014. The GDP growth for the fourth quarter of 2016 was 2.1 percent.
