The problem is that the US emissions standards for NOx are difficult to achieve with a Diesel without spending a lot of money on the exhaust aftertreatment system. New technologies like SCR are helping to an extent, but it all adds cost and complexity to the vehicle.
Current European emissions standards allow higher NOx for Diesel vehicles than for gasoline vehicles, though that will change in the next few years.
