The obstruction allegations against Trump are nonsensical

Sharyl Attkisson:

...
If you were a person of some authority and murdered someone, and prosecutors set out to investigate, and if you spoke publicly against the investigation, proclaiming your innocence and calling the probe a “witch hunt,” and if you worked behind the scenes to use your influence to fire the lead investigator on the murder case — that would seem to be a pretty clear case of obstruction of justice. You, as a guilty man, would be trying to stop authorities from finding out the truth.

But imagine, on the other hand, that you are innocent — accused of a murder you didn’t commit. Not only that, imagine you knew there was no murder to begin with because you saw the victim walking around after the supposed murder. Then, imagine you found yourself the target of the murder investigation by a team that included people who had declared you to be their sworn enemy and expressed strong desires to take you out. Then, imagine this team that included biased investigators began leaking false information to the national media to implicate you in this crime that you knew you didn’t commit.

Imagine that this cloud of the murder you knew was never committed hangs over you, month after month, until it drags on for years. It’s distracting you from your ability and authority to do the job in the public’s interests. But every time you speak publicly to defend yourself and proclaim your innocence, the media and your political enemies declare you to be a liar and say you are obstructing the investigation.

It begins to look like the fix is in.

Under these circumstances, you wouldn’t be human if you didn’t possess a desire to stop a potentially conflicted investigation by your political enemies into a crime that was never committed — least of all by you. Since you are innocent, your attempts to stop an unfair investigation could be fairly seen as an attempt to see justice done, not to obstruct it.

If special counsel Robert Mueller is correct and there was no coordination of any kind between any American and Russia, then the latter analogy seems more applicable to President Trump than the former.

Most of what Democrats call obstruction is just the venting of an innocent man dealing with an illegitimate allegation.   The lack of an underlying crime justifies his frustration with the investigation that is targeting him.
