Sanders spoke on issues ranging from corporate greed, education, climate change and health care.
The Vermont senator and Democratic presidential candidate has spent six straight days aggressively campaigning in the Southland ahead of the June 7 primary.
He will also be interviewed by Bill Maher for a segment on his HBO show "Real Time with Bill Maher."
On Thursday, Sanders spoke at two large rallies in Ventura and Pomona. During his speeches, he talked about a possible debate with Republican presidential nominee Donald Trump.
Earlier in the week, Trump appeared on "Jimmy Kimmel Live!" and said he would consider debating Sanders if the two could raise at least $10 million to go toward charities of their choosing.
Most polls show Bernie Sanders is the overwhelming favorite of millennials - voters between the ages of 18 and 35. But some young voters are taking a serious look at Donald Trump as the primary season rolls on.
Twenty-five percent of people under 30 in a Harvard Institute of Politics poll say they would vote for Trump if he faced off against Hillary Clinton in the fall.
Sanders still has the clear advantage among millennials. The same Harvard poll shows 80 percent of young people with a very favorable opinion of Sanders would vote for Clinton if he drops out.
But many young voters are united in their anger and disillusionment, and both Trump and Sanders have tapped into that subset of voters.
