BS
“Salazar had the option to extend the lease for 10 years after Sen. Dianne Feinstein, D-Calif., included the provision in a rider on an appropriations bill.”
That’s an option and not compulsory. Probably DIFI got lobbied and included an innocuous rider that should the FEDS choose to renew, they can.
After that, looks like they stopped paying their DIFI lobbying fees because the option was not exercised.
Why don’t you post the full version of DIFI’s Rider?
