Above ALL America's citizens are entitled to have a functioning federal justice system, INCLUDING a thorough investigation of Clinton's misdeeds, and even Lynch, Comey, Obama, etc. (emails, tarmac, dossieretc).
Both Trump and Sessions are responsible for that.
Trump has repeatedly tried to prod Sessions into action, to no avail.
My gut is something happened to Sessions on the way to the appointment. I simply cannot fathom going from strong Trump supporter, to undermining him.
I always liked Sessions. But really disappointed in his turnaround.
