Sorry for your loss...but he was a public figure and the event involves massive deception by a Presidential candidate. It WILL be discussed.
It’s so sad that she is more concerned to help Hillary’s campaign than to find out why her son really died. Also, it’s about far more than her son. It’s about the other 3 Americans who died there that night, the dozens more who nearly died, the brave men who risked their lives trying to save her son and everyone present, etc.
Then ofc there are the broader issues of US foreign policy, war on terror, involvement in Libya and the Middle East, etc.
She ought to be a lot more concerned about how to prevent more catastrophes than about protecting Hillary’s campaign from criticism.
