According to the Federal Election Commission, campaigns may not accept contributions from corporations, whether cash or in-kind goods or services. (Its rules do permit contributions from political-action committees affiliated with an organization that pool contributions from affiliated individuals.)
The Republican National Committee on Oct. 16 filed a complaint with the FEC about Twitter, charging that the social-media's moderation decisions about news coverage of Joe Biden and his son Hunter amounted to an "illegal in-kind contribution" to Biden's campaign.
The commission is currently unable to enforce its regulations as it lacks a quorum of members.
