Donald Trump is a neophyte, someone with zero government experience related to the position he competed for, and he has moved toward bringing total neophytes into his close circle.
Rex Tillerson as Secretary of State
Ben Carson as Secretary of Housing and Urban Development
Rick Perry as Secretary of Energy
Andrew Puzder as Secretary of Labor
Betsy DeVos as Secretary of Education
Only Rick Perry has been in government, as Texas Governor, but he is no expert on energy issues, and is best remembered for being unable to name the Department of Energy as one of the government cabinet agencies he wanted to eliminate, were he elected President. And he received Cs, Ds, and Fs in science courses at Texas A & M University!
The other three other than Tillerson are out to destroy the purpose of their government cabinet departments, and Tillerson is a pure corporate guy, who has no background in foreign policy at all, except that he has made business deals with Russian leader Vladimir Putin.
Donald Trump is destroying the whole concept of experience and competence in these and many other appointments he has made, the worst group ever of appointees of any modern President!
