How hard is it to get an intelligence wiretap? Pretty hard.

Wiretaps on Americans in foreign intelligence investigations are not easy to get. And if you’re a candidate for president, it’s even harder.

That’s the experience of current and former senior US officials who expressed disbelief at President Trump’s accusation — leveled without any evidence — that President Barack Obama had the candidate wiretapped at Trump Tower before the November election. Senior officials, who spoke on the condition of anonymity because such matters are classified, said that there had been no wiretap on President Trump.
