Democratic presidential candidate Bernie Sanders toned down his criticism of the Democratic Party and rival Hillary Clinton at two campaign rallies in Northern California Wednesday.

Sanders barely mentioned Clinton and focused his fire largely on presumptive Republican nominee Donald Trump.

He told a crowd in Vallejo Wednesday night that the Golden State’s June 7th primary will be the most important of the entire nominating process.

“Now, I don’t deny for a moment that we have an uphill fight in order to win a majority of the pledged delegates,“ Sanders said. “But we are gonna fight in California and the remaining five other states to get every vote and every delegate we can!”

Earlier, in San Jose, Sanders endorsed a potential November ballot initiative that would legalize recreational marijuana in California.

Sanders also announced that he’s accepted a California debate invitation from Fox News, though there’s been no response from Clinton.

Meanwhile, Clinton’s campaign announced that she will return to California for events on Tuesday and Wednesday of next week.
