Can an employee still deduct unreimbursed business expenses?

Since the new tax law came into effect, employee itemized deductions for unreimbursed business expenses, including mileage, have been suspended.  However, self-employed individuals and certain employees (e.g. armed-forces reservists, certain state or local government officials, educators and performing artists) may continue to deduct unreimbursed business expenses.  Also, the deduction for employee moving expenses has been suspended, but this does not apply to an active-duty member of the armed forces who moves due to a military order.
