I could totally see that if Newsom is trying to bury the news. That's a pretty common tactic - announce late on Friday, too late to hit the "front page", by Monday something else will have happened and it's on page 2.
Why would he try to bury it? Speculating (this is the thread for it), but schools aren't open, No Cal hates So Cal, Smoke everywhere, especially in No Cal. Having the parks open is not as universally anticipated (or accepted) as you might think, especially where he is (and is from).
