Donald Trump has been pushing what he called “unmasking” of the Obama administration for more than three years, but now we are learning what many already suspected—this was a waste of time and taxpayer money. Here’s one of the tweets that started it all.

And just last week Trump seemed to refer to this when he told Fox News the following:

“To be honest, Bill Barr is going to go down as either the greatest attorney general in the history of the country or he’s going to go down as, you know, a very sad situation… I’ll be honest with you. He’s got all the information he needs. They want to get more, more, more. They keep getting more. I said, ‘you don’t need any more.'”

Now, it looks like the end of this investigation could put the president at odds with his Attorney General. The Washington Post reports that the federal prosecutor appointed by Barr “to review whether Obama-era officials improperly requested the identities of individuals whose names were redacted in intelligence documents has completed his work” and found nothing criminal. In fact, they won’t even be releasing a report.

As Dan Rather said, “It was like chasing unicorns through the Land of Oz.”
