“In Sanders’s case, FEC records show he had transferred $4.6 million from his 2016 to 2020 presidential campaign committee as of the end of the second quarter. In his previous presidential campaign, Sanders had somewhat looser fundraising restrictions in place. News reports show he held at least a few events in 2015 where he sought high-dollar donations. Time magazine reported in December 2015: “Sanders has hosted at least nine medium- to high-dollar, closed-door fundraisers in New York, Los Angeles and elsewhere to directly fund his own presidential campaign. Even though Sanders’ efforts sometimes have a proletarian flair — he held one $200-per-ticket fundraiser at a dive bar near a grungy Seattle park — some aspects of the Democratic insurgent’s fundraising are similar to the candidates he condemns.”
