NationofChange FEC sued for not cracking down on dark money group that opposed Sandersâ presidential run Erin Chlopak of the Campaign Legal Center said that this âis yet another example of the agencyâs dysfunction and its disregard for the campaign finance laws it was designed to oversee.â The Campaign Legal Center on Wednesday filed suit against the Federal Election Commission, charging that the regulatory agency has failed to enforce the law against a group that spent millions of dollars on advertisements targeting key voters and opposing 2020 Democratic presidential primary candidate Sen. Bernie Sanders. Though Sanders ultimately suspended his second presidential campaign and endorsed President Joe Biden, the Vermont Independent’s impressive finish in the Iowa caucuses and victory in the New Hampshire Democratic primary were immediately followed by the formation of the Big Tent Project in mid-February 2020.
