The WaPo goes to pains to allude there was collusion, but there wasn’t (FISA warrants are usually granted not because there is a suspicion of something factual). So what does this piece demonstrate? Obama purposely spied on Trump in order to try to find some dirt him. Further, it appears from this story, the spying was vast–as it now has wrapped up yet another member of his team.
In other words, Trump was right again. His tweet was spot on that he was spied on. This is a huge scandal for the breadth of the illegal activity.
