Kozlowski gave him stock tips. Hevesi discussed the perennial impasse in Albany. They watched Jon Stewart and Stephen Colbert together.”Outside, you don’t meet guys like this every day. This place is amazing,””Ja Rule told the Daily News during an exclusive interview at Mid-State Correctional Facility in upstate Oneida, N.Y.
