The Post suggests what may have inspired Trump’s deranged tweets announcing that Obama wire tapped him.

Trump offered no citations nor did he point to any credible news report to back up his accusation, but he may have been referring to commentary on Breitbart and conservative talk radio suggesting that Obama and his administration used “police state” tactics last fall to monitor the Trump team. The Breitbart story, published Friday, has been circulating among Trump’s senior staff, according to a White House official who described it as a useful catalogue of the Obama administration’s activities.

And on the basis of that he makes libelous assertions on Twitter. He skips intelligence briefings, and demands that what intel he does read be kept very short, and instead he relies on right-wing media with minimal ethical standards for his “information.”

Some current and former intelligence officials cast doubt on Trump’s assertion.

“It’s highly unlikely there was a wiretap,” said one former senior intelligence official familiar with surveillance law who spoke candidly on the condition of anonymity. The former official continued: “It seems unthinkable. If that were the case by some chance, that means that a federal judge would have found that there was either probable cause that he had committed a crime or was an agent of a foreign power.”

A wiretap cannot be directed at a U.S. facility, the official said, without finding probable cause that the phone lines or Internet addresses were being used by agents of a foreign power — or by someone spying for or acting on behalf of a foreign government. “You can’t just go around and tap buildings,” the official said.

And you can’t just go around and accuse people of wire-tapping your building on the basis of nothing, either, but Trump thinks rules don’t apply to him.
