Sessions and the FBI are trying to run out the limitations clock, that’s obstruction of justice and yet there is no one other than Trump that can change it. Except of course if the US military or the citizens take action to see that justice is done. And neither of those are likely. No question about it, Congress needs to demand that Trump get rid of Sessions.
That is ludicrous. Do you even know what federal statutes of limitations are? Hint: they are quite long, and there is no statue of limitations for capital crimes.
