Do you think they'll use the Code of Conduct and related clauses in his contract to call this a termination with cause, thereby not having to pay him is $616,000 severance? Now that would be the best-case scenario for sure!
He's only getting severance because they "made a joint decision to part ways". One of those, "We're offering you the opportunity to resign" things. More $ down the hopper. The government is going to have a hard time recovering from this, I think.
