LOS ANGELES -- Jennifer Siebel Newsom, the wife of Gov. Gavin Newsom, took to Twitter late Sunday to post, then delete a message urging people to "stop hating" while her husband has been out of the public eye since canceling plans to attend last month's climate summit in Scotland, according to a screenshot.......When the initial announcement was made Oct. 29, his office said Newsom planned to participate virtually in the United Nations climate summit. But he did not. His last public appearance was Oct. 27, when he received a coronavirus booster shot.
