The campaign of Sen. Bernie Sanders (I-Vt.) says it wont appoint any shrinking violets to the joint task forces developing a compromise policy platform with presumptive Democratic presidential nominee Joe Biden .

Sanders and Biden are creating six task forces on the economy, education, criminal justice, immigration, climate change and health care as a core part of Bidens outreach to the progressive wing of the Democratic Party , Sanders announced when he endorsed the former vice president last week.

The goal is to present a united platform before the convention, influence the kind of personnel who would fill a possible Biden administration and arm Biden with possible executive orders that he could enact quickly should he be elected president.

HuffPost obtained a preliminary list of some of the people Sanders is considering. Everything is still in early stages, and the two campaigns have been negotiating who will be in these six policy groups and how big the groups will be.

The list includes progressive policy experts who heavily influenced Sanders campaign platform over the last year, such as Darrick Hamilton, The Ohio State University economist who has become one of the leading academics on the racial wealth gap in the United States, and Stephanie Kelton, an economist at Stony Brook University who has championed Modern Monetary Theory the idea that governments can never run out of money, and that deficit spending on major domestic programs would lead to economic growth.

Though not exhaustive, some other names on the Sanders campaigns early list include Heather Boushey, an inequality expert with the Washington Center for Equitable Growth; Emmanuel Saez and Gabriel Zucman, two leading economists in the world of wealth inequality and progressive taxation; Jeffrey Sachs, who runs Columbia Universitys Center for Sustainable Development; Josh Bivens, an economist with progressive think tank Economic Policy Institute; Daniel Kammen, who runs the Renewable and Appropriate Energy Lab at University of California, Berkeley; Tara Raghuveer, an affordable housing activist who runs the Kansas City Tenants group; and Bonnie Castillo, the executive director with the National Nurses Union.

Faiz Shakir, Sanders campaign manager who has been negotiating with the Biden campaign for weeks, would not confirm that the campaign was considering these individuals. These task forces are not yet finalized and could consist of a mix of campaign staff and outside experts. HuffPost reached out to every person on the preliminary list. Sachs and Kammen said they had not heard from either campaign. Boushey and Kelton declined to comment. The others did not respond.

Shakir said the Sanders campaign will put forward people who are experts that are going to represent the ideologies of the respective candidates.

There are no shrinking violets here, he said, adding that Bidens team has been very receptive to their suggestions.

A Biden campaign aide echoed the sentiment, saying the task force will represent the diverse viewpoints of the Democratic Party.
