U.S. economic growth accelerates in 2nd quarter

That's more than the 1.9% rate economists had expected for the second quarter. Jeff Stein, White House economics reporter for The Washington Post, joins CBS News to explain what the GDP growth says about the economy, and how the Federal Reserve could read the data.
