"The American people will not vote for a presidential candidate who insults women every day, who insults veterans and who insults African-Americans," Sanders said Friday during a rally in Portland, Ore.
Sanders also took a few shots at Clinton, questioning her reliance on super-PAC funding and criticizing her for not releasing the transcripts of her paid speeches to Wall Street companies.

Sanders drew big applause when he said he would “phase out” hydraulic fracturing, or fracking, in which pressurized water and chemicals are injected into the ground to release oil and natural gas.
The Vermont senator panned Clinton's stance, saying she “strongly supported fracking around the world and still supports it around the country.”
At a March Democratic debate, the former secretary of State said she opposes some individual fracking operations based on a series of conditions.
“By the time we get through all of my conditions, I do not think there will be many places in America where fracking will continue to take place,” Clinton said at the time.
The Portland audience erupted into cheers when a bird flew down toward Sanders as he spoke.
As the bird landed on his podium, Sanders said: "I know it doesn’t look like it, but that bird is a dove asking for world peace. No more wars."
He closed with a call for support heading into Washington state's caucuses Saturday and Oregon's primary in May.
“It’s my hope and belief that Washington and Oregon are prepared to lead this country into a political revolution,” Sanders said. 
“Washington and Oregon can help transform this country. Let’s do it.”
Alaska and Hawaii are also voting Saturday.
