I became an employee half through the year, can I only deduct mileage from when I was an IC even though as an employee I also drove?

Basically the job is similar to a paper route. I drive and perform services. the company I was an IC for was bought and the new owner made all the drivers employees. I used my personal vehicle for this job the whole year, both when I was an IC and continued after I was an employee.

1. Does the mileage deduction need to be split between the "business" and the time I was an employee? I can't put it all under the IC's business right?

2. Can an employee deduct mileage? How?
