Fourth quarter 2014 real GDP was revised 0.4 percentage points lower to 2.2%.  That's quite disappointing, although still mediocre growth.  The reason for the revision reduction was inventories did not grow nearly as much as originally estimated and imports increased.  Real consumer spending was barely revised.  Overall Q4 GDP cutting isn't that surprising, more Q3 GDP's lack of trade deficit impact was.

As a reminder, GDP is made up of: Y=C+I+G+{\left(X-M\right)} where Y=GDP, C=Consumption, I=Investment, G=Government Spending, (X-M)=Net Exports, X=Exports, M=Imports*.  GDP in this overview, unless explicitly stated otherwise, refers to real GDP.  Real GDP is in chained 2009 dollars.
