You’ve heard it said, no doubt, that someone with something to hide “doth protest too much” at the hint of questions about whatever it is he or she might be hiding.

It’s a Shakespearean statement, coming from “Hamlet.”

So it could be with Donald John Trump, who’s forgoing his “unity” pledge with another series of tweet tirades against special counsel Robert Mueller’s investigation into whether the Trump campaign colluded with Russian operatives to influence the 2016 presidential election.

The president detests Mueller. He wants him out, or so many have speculated. Trump just might do something seriously foolish by asking deputy Attorney General Rod Rosenstein to remove Mueller. Or, he could do something even more foolish than that by removing Rosenstein and Mueller in one fell swoop.

Here’s my Trump question of the day: If the president is innocent of any of the allegations leveled against him, why not let Mueller do his job — after releasing every single shred of information he would ask of the president, his campaign team and his White House organization?

If he’s clean, the record will show it. Isn’t that how it works?
