Donald Trump is trying to bring into politics a phenomenon that’s taking off in college athletics: money for use of the former president’s name, image and likeness in campaign ads.

In a letter this week, the Trump presidential campaign asked all down-ballot GOP campaigns for at least a 5% cut of the money raised from advertising that features the party’s 2024 presumptive White House nominee.

“We ask that all candidates and committees who choose to use President Trump’s name, image, and likeness split a minimum of 5% of all fundraising solicitations to Trump National Committee JFC,” said the April 15 letter signed by campaign co-campaign managers Susie Wiles and Chris LaCivita.
