This is probably a lie. We should ignore it.
Trump's campaign claims that someone spearfished one of their staff, got access to their internal servers, and then copied hundreds of sensitive internal documents.
Bullshit.
Trump's campaign claims Iran hacked them, but they won't say how they know it was Iran. Why would a hacker steal Trump's documents, but then share them only with Politico, a right-wing outlet that wouldn't publish anything damaging to Trump?
