From The New York Times: Federal candidates can appear as “featured guests” of super PACs, but whether a super PAC can also pay for transportation is less clear cut. Super PACs are not allowed to coordinate with campaigns, and campaign finance experts say that Mr. DeSantis’s arrangement — in which he is campaigning for president as a guest of a super PAC — could test that rule.

“I think what DeSantis is currently doing is an abuse of this law to benefit his candidacy — paid for by his super PAC and its special-interest donors,” said Saurav Ghosh, a former Federal Election Commission lawyer and the director of federal campaign finance reform for the Campaign Legal Center.
