If President Obama had ordered an FBI investigation to stop: It would have been a legal order. He would have been 100% within his constitutional powers.
Whether it would have been a politically smart move, is a different and legitimate question.
Whether he would have been covering something up – or maybe not – is a different and legitimate question.
Whether Congress and/or media and/or citizens should then investigate whatever he MIGHT have been covering up, is a different and legitimate question.
Whether he would have been right morally, is a different and legitimate question.
Whether Congress should then try to punish him, via censure or impeachment – or maybe not – is a different and legitimate question.
But would Obama’s order, as such, have been a crime of obstruction? No. Because here in America, we have something called a “constitution” which creates “separation of powers” including a unitary “executive branch”, in which the FBI resides.
The FBI does not reside in the legislative branch (Congress).
The FBI does not reside in the judicial branch (Supreme Court).
The FBI resides in the executive branch and, at the end of the day, follows the policies and orders of a chain of command that goes to the Attorney General and then to the President.
That is how the U.S. system of government works. Obama could have literally ordered the Hillary Clinton e-mail investigation to stop, and he would have been within his legal powers. (But again: the optics, morality, and how Congress and the citizenry should follow up on his order, would be different and legitimate questions.)
Now, substitute “President Trump” for “President Obama” in the above, and do the math. We’ll wait.
After that, we can turn to fact that President Trump actually never ordered any FBI investigation to stop.
Which fact means that you, lefties, are working yourselves up – and dividing America with your hate-filled hysteria on the Comey-Flynn matter – and making deadly (or potentially deadly) assaults on your fellow Americans – for nothing.
