It's a screenshot from FlightRadar24, but I can't find that plane having been flying. Not unreasonable that they would have been but their conclusion that it's an indication of sustained operations is pretty tenuous, there's lots of reasons for a tanker to be up (and the planes appear to have been withdrawn from VZ airspace so it's a moot point out).

Someone's getting absolutely obliterated for leaving their transponder on if it's legit, though.
