It was Democrats who nearly a decade ago first labeled the opaque funneling of millions of dollars into various political influence operations “dark money” and railed against the then-GOP-dominated practice.
Over the past two election cycles, however, Democrats have not only caught up but surpassed Republicans in channeling unlimited sums of special interest and billionaire spending through nonprofits that do not disclose their donors’ identities.
Liberal groups and political operatives allied with the Democratic Party have also grown more creative in the types of political influence operations the funds support. A little-noticed dark-money entity created at least three years ago to help Democrats in Congress work more effectively is now drawing scrutiny.
During the final years of the Trump administration, a small but powerful group of former Democratic congressional aides and Obama administration appointees created an organization to help House and Senate Democrats exercise their oversight authority over the executive branch. The group is funded through the largest liberal dark-money channel in the country: Arabella Advisors.
Called “Co-Equal,” the group at first aimed to assist Congress in exercising its power as a branch of government equivalent to the executive, helping Democrats rebuild their oversight muscle to investigate the Trump administration.
