In March 2017, the Trump administration cited the "Heat Street" and BBC stories as evidence for Trump's claims on Twitter that President Barack Obama had illegally wiretapped his phones. According to Kessler the BBCs account differed substantially from that of Mensch, the BBC alleging that: "Neither Mr Trump nor his associates are named in the FISA order, which would only cover foreign citizens or foreign entities — in this case the Russian banks." Kessler stated: ""The Washington Post" for months has sought to confirm this report of a FISA warrant related to the Trump campaign but has been unable to do so. Presumably, other major news organisations have tried to do so as well. So one has to take this claim with a huge dose of skepticism." Kessler added that the assertion that the FISA warrant was to examine possible activity between two Russian banks and a computer server in Trump Tower had not been confirmed by U.S. news organisations, and that the Trump Organisation server communicating with Russian banks may have actually been located in Philadelphia, not Trump Tower. Moreover, according to the FBI as reported by "The New York Times" in October 2016, "there could be an innocuous explanation the server traffic, like a marketing email or spam."
