The Department of Homeland Security's inspector general has referred an internal investigation into Federal Emergency Management Agency chief Brock Long's frequent commutes to North Carolina to federal prosecutors for possible criminal charges, The Wall Street Journal reports, citing people familiar with the investigation. Long and two other FEMA employees may have broken as many as six laws by traveling from Washington, D.C., to Long's home in Hickory, North Carolina, in a caravan of government vehicles. The aides who traveled the 400 miles with Long for his long weekends at home stayed in hotels, at taxpayer expense, the inspector general's office found.
