I've been giving this some thought, and there is just no way any of these over inflated wind bags are going to take their own lives. Their ego is much to large to ever even contemplate the act. They suicide other people not themselves.
However, literally taking your own life is not the only way to commit suicide. You could do something stupid like indict, and arrest the real President of the US putting the final nail in your treason and sedition coffin thereby guaranteeing that you receive a death penatly for your crimes.
Someone's else suicides them,to clean up the witnesses.....
I think that might also be a possibility. They sure don't mind sacrificing the pawns. I'm not sure they would try that in those higher in their organization. They fail and the intended targets squeal like a pig.
