Sounds like income tax issues. Her accountant should have shored those claims up.
Now how she was able to buy $1m worth of property on a government employee’s salary is another issue.
There is more to this story that isn’t being reported. The main claim is she took out a $40K early withdraw from her pension on false claims to avoid a federal $4K tax penalty. That is chicken feed.
Her government salary is a quarter million dollars per year.
