US President Joe Biden has thrown his support behind California Governor Gavin Newsom, on the eve of a vote that could remove the governor from office.
At a rally in Long Beach, Biden said the result would "reverberate around the world".
Polls show a comfortable lead for the Democrat, whose main rival, Larry Elder, is a conservative radio host.
Newsom was democratically elected and took office in 2019, but Republicans hope to unseat him early.
It is only the second-ever recall vote for a governor to appear on the ballots of the Democratic state.
