A Legal question about sexual harassment and the EEOC

If a paid teaching assistant was sexually harassed by a professor would it fall under the EEOC rules?

What if the TA was an unpaid student, would EEOC rules still apply?

Thanks!

Assuming this is in a university or college setting, there should be ample local resources to help.
