I just answered “yes” to one of those “online polls” posted on MSN.com’s home page.

The question was this: Should there be an investigation of Trump’s allegation of wiretapping by the Obama administration?

Why “yes”? Why endorse the idea of a probe?

It’s simple. I don’t believe for an instant, a nanosecond, that President Obama was in any way responsible for any kind of wiretap of Trump Tower. I believe that Donald J. Trump made it up. He fabricated an allegation to divert attention from other matters plaguing his administration.

This is the president’s modus operandi, as he’s demonstrated time and again since announcing his candidacy in the summer of 2015. The heat gets too warm under his backside, he fires off a tweet making an outrageous declaration.

He did so again this past weekend with that ridiculous tweet accusing President Obama — with zero evidence — of “ordering” a wiretap, which of course he cannot do legally. Someone, according to Trump, tapped his Trump Tower offices looking for evidence that his campaign had inappropriate or illegal contact with the Russian government, which intelligence authorities have concluded sought to influence the 2016 election, to help Trump get elected.

I realize a congressional investigation — which Trump is seeking — would be costly. I also realize it would divert members of Congress from the myriad other tasks that await them, and for which the public already is paying them good money to address.

You know, things like the budget, national defense, public education — not to mention the many individual concerns that can be found that are unique to each of 435 congressional districts and in each of the 50 states.

If such a probe is done in a bipartisan manner, then I truly believe it would expose Trump to be the fraudulent, petulant liar many millions of us believe him to be.

Not that it would dampen Trumpkins’ enthusiasm for their guy.

Just get it on the record.
