On the Q bit in the White House meeting with the President.
The first Q is not a question from the media. It is a direct answer from (Jon) to the the President. A declarative statement.
"THE PRESIDENT: Jon, you know Jim Brown? The greatest of all time.
Q It’s an honor, sir."

Yes, it could be a reporter or WH staff and since they weren't headlined, included in the Q section vs specifically named.
However, plausible deniability, me thinks.
