So Obama is claiming that HE never authorized a tap on Trump's phone. He failed to say that Trump's phone was never tapped, he just said he didn't do it. Old Harry Truman would not have seen it that way. If any government agency tapped Trump's phone, then Obambi is responsible, at least as long as he was in office. There is a report out on TV saying that the rubber stamp FISA court DID issue a warrant to tap Trump's phone. Nobody has denied that report, yet. If the report is true, then Trump's charge of wiretapping is true. And Obambi is doing a weasel. As usual.
TV is doing a long song and dance about the FISA court and what it can or cannot do, aimed to showing that the court won't do a wiretap on just the president's sayso. Since the court meets in secret, the justices are secret, and the records are secret, it can do anything it wants. And probably has.
