Today might be the day when the president of the United States delivers the goods on what he knows — allegedly — about a so-called wiretap ordered by President Obama on the Trump Tower offices.

The U.S. House Intelligence Committee reportedly has sent a letter to the White House asking for evidence that Donald J. Trump has to back up his allegation that Obama tapped the New York campaign offices to search for proof that Trump was colluding with Russian government officials who sought to influence the outcome of the 2016 election.

Trump hasn’t provided any proof. House Intelligence panel officials want to see it.

Is this a firm deadline? Ohhh, probably not. But the president needs to provide proof of the incendiary accusation he has leveled against his immediate predecessor. He has accused Barack Obama of breaking the law, committing a felony. That’s what this clown does; he says things to garner headlines without any substantiation.

Absent any proof we are left to wonder out loud about what the president is trying to do. Why in the world does he do these things?

Is this act alone — a reckless accusation that the former president has broken the law — an impeachable offense? There’s some chatter that, yes, it is. I am not prepared to jump on that haywagon.

This president, though, has demonstrated graphically a willingness to say anything, to damage anyone. He has yet to demonstrate an ability to corroborate his fiery rhetoric.
