dated yesterday ?
Q and A at Congressional hearings are negotiated and agreed to ahead of time. Not much straying from the script is permitted.
Thats why such hearings are frustrating to outsiders, obvious follow-up questions arent asked, members paying no attention, reading from scripts, etc. Even the swearing in is just theater as its illegal to lie to or mislead Congress regardless of oath (unless youre a Leftist).
The words used today were released yesterday.
