Paul J. McNulty, the U.S. attorney on a mission to crack down on federal procurement fraud is now looking at Orbital Sciences Corporation, executing search warrants at two of the space contractor's offices last week.

As government contracting attorneys know, McNulty announced the formation of the Procurement Fraud Working Group in February (the day Boeing CFO Michael M. Sears was sentenced to four months in prison for illegally recruiting an Air Force official, and as investigation of Boeing continued).

Orbital has released a statement saying "it is not aware that it has violated any federal contracting laws, policies or procedures" and is of course fully cooperating with the investigation. Stay tuned.
