First-- as I said, I have great respect for Senator Wyden. I thought, though in retrospect, I was asked-- "When are you going to start-- stop beating your wife" kind of question, which is meaning not-- answerable necessarily by a simple yes or no. So I responded in what I thought was the most truthful, or least untruthful manner by saying no.

And again, to go back to my metaphor. What I was thinking of is looking at the Dewey Decimal numbers-- of those books in that metaphorical library-- to me, collection of U.S. persons' data would mean taking the book off the shelf and opening it up and reading it.

Apparently, "any data at all" does not include call record information, just content. Also,

And this has to do with of course somewhat of a semantic, perhaps some would say too-- too cute by half. But it is-- there are honest differences on the semantics of what-- when someone says "collection" to me, that has a specific meaning, which may have a different meaning to him.

"Collection" does not mean collection.
