The contract expired today, but had an option period through March of 2026. DHS just needed to exercise the option.
Edit: Note the contract ended today April 16 - so performance would stop midnight tonight if the option wasn't exercised. Government contracts routinely go down to the wire like this, and often are late getting exercised. Why the uproar over this one? Did CISA signal to MITRE that they weren't going to exercise the option?
