California Governor Gavin Newsom has disappeared from public view for 10 days and abruptly canceled plans to attend the COP26 climate summit in Scotland over unexplained ‘family obligations.’

Newsom was last seen in public on October 27, receiving a COVID-19 booster shot in Oakland. He said it was painless and then flexed in celebration, urging others to get boosters as well.

Two days later, his office issued a statement citing unspecified family obligations, abruptly cancelling his plans to attend the global climate conference, a huge gathering of international leaders on a subject that is among his highest priorities.

The statement claimed that Newsom would attend the summit virtually, though he still has not made a video appearance. California’s lieutenant governor led the delegation in his place. No further information on the ‘family obligations’ that caused the sudden alteration to his schedule have been shared.
