As Liborgate spreads from Britain to the United States, the Justice Department is working on criminal cases against "several financial institutions and their employees," reports DealBook.

Add these pending criminal charges to the growing slate of class action lawsuits brought by investors and city governments, and the litigation bill for big banks could end up as high as $6 billion
