Ivanka is a government employee, she just doesn’t have a salary.
She was made an employee because as an advisor to Trump she has access to classified data and there were ethics concerns.
We don’t know yet if she emailing classified data over her personal account.
She and her lawyer say no AND they also notified Congress long ago.
