Nunes did not say that Trump's phones were tapped. He said exactly the opposite of what you have desperately and erroneously concluded from this article. "Incidental" means that Trump was recorded while talking persons who were under surveillance as part of a national security investigation. Telephone conversations have two or more parties. If the phone of one of those parties is tapped, then everyone who is part of the conversation is recorded. That's what "incidental" means. Before you start mistakenly gloating, you might ask why Trump is talking to people who are subjects of  FISA approved wire taps and what those conversation might reveal. This is NOT good news for Trump.
