In the time since President Trump’s March 4 tweets alleging he had his “‘wires tapped’ in Trump Tower” shortly before last year’s election by President Obama, there’s been no evidence revealed that strictly supports his claim. Trump opponents view this lack of evidence as proof the president made it up as a distraction. Republican House Intelligence chairman Devin Nunes’s disclosure last week about “incidentally collected information” of Trump associates by the intelligence community suggested there could be a nugget of veracity to Trump’s claim. Trump himself said he felt “somewhat” vindicated, even if Nunes himself says what he discovered was not a wiretap of Trump or Trump Tower.

Unfortunately, clarity on this issue—what occurred, why it occurred, and whether any of it was illegal or improper—has been hard to come by. All parties seem to have taken advantage of the partial picture for their own political purposes. And Monday’s revelation that one of Nunes’s sources for the relevant intelligence reports was in the White House complex only added more confusion to the equation.
