Trump Tweets: "Terrible! Just found out that Obama had my "wires tapped" in Trump Tower just before the victory. Nothing found. This is McCarthyism!Terrible! Just found out that Obama had my "wires tapped" in Trump Tower just before the victory. Nothing found. This is McCarthyism!"
The Press (and the Left - I know those terms are redundant, but I still need to keep using them) want to hold Trump to precise language. In a Tweet. They think a Tweet is the same as a carefully crafted, precisely chosen worded statement. To them, the Tweet of "Obama has my" means Obama personally ordered that Trump's personal phone lines be tapped. They leave no room whatsoever that the Tweet might mean something else, like someone in the Obama administration (i.e., members of the the Justice Department and/or the FBI) put some kind of surveillance on telecommunications lines in Trump Tower for people in or around the campaign or associated with the campaign.
At the same time, the Press (et al) take former DNI James Clapper's statement at face value as being broad and all encompassing. "For the part of the national security apparatus that I oversaw as DNI, there was no such wiretap activity mounted against the President-elect at the time, or as a candidate, or against his campaign."
It's important to note that the DNI doesn't oversee the Department of Justice or the FBI. The only parts of the DoJ and FBI that is directly under DNI oversight is the Office of National Security Intelligence, a department under the DEA under the Justice Department, and the Intelligence Branch of the FBI, a department of the FBI, also under the Justice Department. So anyone in any other department of DoJ or the FBI could have executed a FISA warrant and that would have been completely out of the purview of Clapper.
The also take the statement from Obama's camp as the same pedantically precise gospel, from Obama spokeman Kevin Lewis: "A cardinal rule of the Obama Administration was that no White House official ever interfered with any independent investigation led by the Department of Justice. As part of that practice, neither President Obama nor any White House official ever ordered surveillance on any U.S. citizen. Any suggestion otherwise is simply false."
There were a whole lot of people in the Obama Administration that weren't necessarily Obama and weren't necessarily a White House official. Every single member of the Department of Justice and the FBI fits into that category, for example.
I can imagine a scenario where the President (be it Obama, Trump, or any other President) says to someone at Justice, "See if there's anyway you can wrangle a wire tap on Joe Blow. Not an order, of course, but if the opportunity presents itself, that would be great. <wink wink, nudge nudge>"
Incidentally, FBI Director James Comey has (reportedly) asked the Justice Department to refute Trump's wiretapping claim, and the Justice Department refused. And isn't that interesting.
Personally, as unlikely as it is, I think it's far more likely that there was a wiretap in Trump Tower than there is that anyone on the Trump campaign team colluded with the Russians to influence the election. The Trump campaign simply wasn't prepared or organized enough to do something like that, and not have it already factually known that it happened. So far, even according to Clapper, there is no evidence whatsoever that there was any collusion at all between the Russians and anyone in or related to the Trump campaign.
