Is a candidate raising money for an outside group?
Candidates may try to get around anti-corruption laws that prohibit them from raising large sums of money by appearing at fundraising events for super PACs and dark money groups — and having other people explicitly ask for contributions. Unlike candidates’ own campaigns, super PACs and dark money groups can accept unlimited amounts of money from individuals, labor unions, and corporations.
Additionally, candidates sometimes explicitly endorse outside groups that are spending money on their behalf, which sends clear signals to moneyed interests that large contributions will be rewarded with access and influence.
