Cabinet members are alter egos of the President, so should be the Vice President

AL S. VITANGCOL III

AN alter ego can be thought of as a person’s clone or second self. A professional alter ego might be a trusted aide who knows exactly what the boss wants done. A personal alter ego might be a close friend who is almost like a twin.” This is how Merriam-Webster dictionary defines an alter ego. It was included as a part of the English language sometime in 1537.
