He will mock his voice constantly, and say "I'm Scott Malkinson. I have diabetes"
What do I do if this kid in my class keeps making fun of another kid for having diabetes?

You pull him aside when everyone else is not around and talk to him. Explain to him that it is not nice to make fun of people, especially if they are going through something.
If he doesn’t listen after you talked to him alone, and he keeps making fun of the other child, call his parents.
Make fun of the kid that is bullying the other kid and get others to join in
