You are the president. You can appoint anyone you wish to fill staff positions and whatever other positions are unilaterally your decision without anyone's permission.
Do you automatically NOT HIRE ANY RELATIVES to avoid the appearance of neopotism?
WHAT IF
a relative happens to really be best for the job? Best education best experience best record? Do you not hire a person whom you believe would do the BEST job just because he/she is a relative?
Well?
