Just wondering: Can’t POTUS get proof if he demands it?

The thought occurs to me this morning …

If the president of the United States accuses his predecessor of a crime, can’t he gather up the proof of that allegation on demand? Can’t the president call the spooks, the spies, the prosecutors, anyone who can prove something happened and then produce the proof of what he has alleged.

Donald Trump’s tweet over the weekend that Barack Obama ordered a wire tap on Trump Tower offices has ignited the mother of political firestorms. The president hasn’t proved anything. He has offered nothing but a tweet that said “it is a fact” that his predecessor ordered the wire tapĀ because of some belief that there might be collusion between the Trump campaign and the Russian government to influence the outcome of the 2016 presidential election.

A fact? Is that what you say, Mr. President?

Sir, you are in command of the world’s greatest intelligence network — no matter what you have said about it. I believe you are able to obtain proof on demand.
