Jake Sullivan was Hillary Clinton's Deputy Chief of Staff at the State Department.  He was 
 among the inner circle staff who supported her in exclusive use of a secret, private server and email accounts for ALL of her work-related emails as Secretary of State.   He was among those who were "extremely careless," according to the FBI, in handling of classified information. 

Intensely partisan,  more loyal than able, Sullivan continued to support Hillary in her campaign for president in 2016 as her top foreign policy advisor.   He has fully embraced Hillary Clinton's delusion, dishonesty, deception, corruption and HORRENDOUSLY bad judgment, well compensated to say "YES, YES, YES, m'am." 

Why would anyone ask, listen to, respect or trust anything Jake Sullivan has to say about national security?
