Former President Donald Trump’s campaign has found a new way to press for badly needed cash.

In a letter received by Republican digital vendors this week, the Trump campaign is asking for down-ballot candidates who use his name, image and likeness in fundraising appeals to give at least 5 percent of the proceeds to the campaign.

“Beginning tomorrow, 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. This includes but is not limited to sending to the house file, prospecting vendors, and advertising,” Trump co-campaign managers Susie Wiles and Chris LaCivita wrote in the letter, which is dated April 15.

They add: “Any split that is higher than 5% will be seen favorably by the RNC and President Trump’s campaign and is routinely reported to the highest levels of leadership within both organizations.”

The letter comes as Trump is struggling to close a fundraising gap with President Joe Biden. Biden’s campaign has said that it has raised over $190 million, more than double what Trump has taken in. Trump’s campaign has acknowledged that it will be outraised by Biden, though it has been looking to make up ground, with large and small donors alike. By asking Republican candidates to break off a chunk of their proceeds, the Trump campaign would enlarge its bank account.
