Wall Street weighed down by banks, energy stocks

Wall Street was lower on Friday as a drop in oil prices weighed on energy stocks and as financials came under pressure in the wake of a massive $14 billion fine slapped on Deutsche Bank. The far bigger-than-expected penalty was levied by the U.S. Department of Justice to settle claims that the German bank missold mortgage-backed securities. Deutsche Bank's U.S.-listed shares were down 9 percent.
