Good job Senator! Now what about this?
Trump’s alt-right hand Steve Bannon was given a seat on the 
National Security Council’s Principals Committee which is  against 
Federal Law 50 U.S. Code § 3021
See it with your very own eyes 
https://www.law.cornell.edu/uscode/text/50/3021
It says:
The Council shall be composed of—
(1)the President;
(2)the Vice President;
(3)the Secretary of State;
(4)the Secretary of Defense;
(5)the Secretary of Energy; and
(6)the Secretaries and Under Secretaries of other executive departments 
and of the military departments, when appointed by the President by 
and with the advice and consent of the Senate, to serve at his pleasure.
Note that the list does not mention local neo-nazi adviser. 
Senate has power to prevent this.
