The report comes from the non-profit foundation ProPublica and says Democrats secretly influenced the independent citizens' panel that drew the state's new political districts.
According to the report, Democrats drew their ideal districts and presented maps to the panel through proxies.
The California Democratic Party chair John Burton told ABC7 that the "party didn't do this" and charged ProPublica didn't contact them before releasing the story.
So far, there has been no response from state Republican leaders.
