LOS ANGELES — The Democratic National Committee will hold what it is billing as a “Resistance Summer” rally at USC today in a bid to engage, mobilize and organize voters to turn their grass-roots energy into electoral victories.

Rep. Keith Ellison, D-Minnesota, the DNC’s deputy chair, Vice Chair Maria Elena Durazo, Secretary Jason Rae, Assistant Treasurer Lorna Johnson, Rep. Ted Lieu, D-Torrance, and California Democratic Party Chairman Eric Bauman are set to speak at the 5 p.m. rally at United University Church on the campus.

Following the rally, speakers and attendees will call voters in Arizona urging them to contact Sen. Jeff Flake, R-Arizona, and demand his opposition to the Senate Republican health care bill.

The Resistance Summer program is a nationwide Democratic Party initiative designed to bolster state parties by investing in local organizing projects.

The rally “is about engaging with the grass-roots organizers to put a stop to the Republican assault on the Affordable Care Act,” Vedant Patel, the DNC’s western regional press secretary, told City News Service.

Supporters of Sen. Bernie Sanders, I-Vermont, plan a news conference preceding the rally to criticize the Democratic National Committee and California Democratic Party for “sabotaging” the single payer health care plan embodied in SB 562, according to a Facebook posting.

“We will hold signs and chant, then go inside to see what they discuss,” the posting said.

“If it’s all Trump and Russia, we will tell them that they must put forth a positive program including single payer, and we will tell Bauman to use those relationships with party leaders he touted during his campaign to move SB 562 out of the (Assembly) Rules Committee.”

Christiana Purves, a Republican National Committee regional communications director, called the rally a “stunt” that “is just another example of how the Democrat Party is in utter disarray and offers nothing to voters but obstructionist rhetoric.”

“Democrats would rather play games at the expense of the American people, than present a viable solution to our broken health care system,” Purves said. “As demonstrated by Bernie supporters protesting today’s resistance event, voters expect more out of their representatives.”
