The U.S. economy grew at a 2.8 percent annual rate in the final three months of last year, the fastest growth in 2011, according to the Commerce Department, Friday, Jan. 27, 2012. Americans spent more on cars and trucks, and companies restocked their shelves at the strongest pace in nearly two years. But growth in the October-December quarter — and all of last year — was held back by the biggest annual government spending cuts in four decades. (AP Photo/Paul Sancya, File)
