Why is it surprising that someone in the Goverment Sector being foreclosed on is being laid-off?
People with fiancial problems have always been considered a security risk. Whether foreclosure consitutes an actual risk, many people just walk away with little debt, this is one of the benchmarks that the goverment looks at as to your employabilty (previous and current).
The goverment simply does not want you in a position where your loyality could be comprised by finacial gain.
This is not new news and is standard policy since at least the 50s.
