In what's shaping out to be a pretty dreadful year for Jesse Jackson Jr., the Chicago congressman who has been on medical leave for bipolar disorder is now the subject of a criminal investigation for misusing campaign money to spruce up his house. 

The Wall Street Journal's Devlin Barrett and Evan Perez report that a FBI probe of Jackson is in its "final stages ... according to people familiar with the matter," with the possibility of an indictment coming before the November election.
