Moreover, Trump cannot order investigations, or halt them. You know this. Even when Trump casually mentioned to that slime ball Comey that General Flynn, a highly decorated officer, was a "good guy", the press and the Democrats wanted him crucified for it.
No, it is up to Jeff Sessions to uphold the law, and he flat out refuses to do so.
Trump knows the Clintons are corrupt as any politicians in history. He told Hillary she should be in jail at the debates. He isn't stupid. He knows their crimes. And for someone as savvy as he is, I highly doubt he was influenced by Chelsea, a.k.a: "The Clinton Foundation Illegally Paid for My $3.5 Million Dollar Wedding."
Moreover, Trump is livid at Sessions (still) for his cowardly recusal.

Sessions gave up the authority of being Attorney General only weeks into Trump's Presidency, and when he did so, Sessions crossed the Rubicon. He can never be an effective Attorney General.
He must go.
