OMAHA, Neb. (AP) — Billionaire investor Warren Buffett said Thursday that U.S. economic growth has slowed in the last two months as fears about Europe’s debt woes mounted.

Buffett’s comments during an interview Thursday on the cable TV network CNBC contrast with what he has been saying for a couple years. Buffett has said the economy was gradually improving since the fall of 2009 in every area except businesses related to housing.
