A foreign company hired by the U.S. government to mentor and train Afghan intelligence officers billed Uncle Sam for more than $50 million in luxury cars - including Porsches, an Aston Martin, and a Bentley - and the lucrative salaries of executives and their spouses (who didn’t do any work). The firm also spent $1,500 on alcohol and $42,000 on automatic weapons prohibited under the terms of the contract, according to figures provided by a U.S. Senator from a federal audit that has not been released to the public.
