They join a sprawling catalog of Trump-branded merchandise, ranging from steaks to scented candles, that the businessman-turned-president has licensed over the years.

But as his campaign coffers dwindle and his fortune comes under threat, Trump ÔÇö who has never completely severed his political career from his financial one ÔÇö is now actively intertwining his business ventures with his White House bid.

“There is no precedent for this level” of business activity during a presidential campaign, Harvard Law School Professor Lawrence Lessig told CNBC, though “the trend has been building for many years.”

Brendan Fischer, deputy executive director of money-in-politics watchdog Documented, agreed.

“I can’t think of any other modern example of a presidential candidate hawking an array of goods for their private benefit,” Fischer said.

For an average candidate, that activity might trigger a campaign finance investigation ÔÇö but it likely won’t for Trump, who has been selling branded goods long before he entered politics, according to Fischer.

“Trump is a unique case,” he said.

That uniqueness was on full display Tuesday, as Trump unveiled his latest promotion: a $60 Bible that includes copies of the nation’s founding documents, along with lyrics from country star Lee Greenwood’s hit song, “God Bless the U.S.A.”

The song by Greenwood, who is partnering with Trump to endorse the high-priced holy book, is a regular needle drop at the presumptive Republican nominee’s campaign rallies.

Trump made the campaign connection even more explicit in a video announcing the promotion, warning that Americans’ rights are under threat and declaring, “we’re gonna get it turned around.” He also invoked his campaign slogan, “Make America Great Again,” multiple times.

It is unclear how much money Trump is making off the Bible ÔÇö he is receiving royalties from its sales, a person familiar with the arrangement told The New York Times ÔÇö but whatever he gets will be effectively going into his pocket.

The website for the Bibles says it has no link to Trump’s campaign. It instead uses Trump’s name, likeness and image under paid license from a company called CIC Ventures LLC.

Trump’s 2023 financial disclosure calls him the “Manager, President, Secretary, & Treasurer” of CIC Ventures, and lists his revocable trust as the sole owner of the company. Trump has made more than $5 million in speaking engagements through the company, the disclosure shows. Florida business records show CIC’s address is the same as Trump’s golf club in West Palm Beach, Florida.

Lessig noted that Trump’s business moves do not appear to be violating campaign ethics or financial rules.

“I don’t think there’s any ethical problem with it at all ÔÇö so long as the proper reporting requirements are complied with,” the professor said.

“There may well be a strategic or brand problem with it, but that’s the same as with any political speech,” he added.

Trump campaign spokesman Steven Cheung told CNBC, “These successful business deals are completely separate from the campaign.”

Trump’s Biblical endorsement came during Holy Week, the run-up to Easter and a sacred time for Christians. It also came less than six weeks after Trump traveled to a sneaker convention in Philadelphia to launch his own line of tennis shoes.

The aptly titled Trump Sneakers range in price from $199 up to $399 to preorder. Two of the available styles are decorated with the number 45, a reference to Trump’s tenure as the 45th U.S. president.

That website selling the sneakers also advertises Trump-branded “Victory47” cologne and perfume, both of which cost $99.

“‘Victory’ is the signature scent of strength and success, encased in a luxurious gold bottle,” the site’s description of the cologne reads.

Trump’s appearance at the convention further blurred the line between campaign outreach and capitalist enterprise.

“We’re going to turn this country around fast. We’re going to turn it around. And we’re going to remember the young people, and we’re going to remember Sneaker Con,” he told the crowd, which greeted him with a mix of cheers and boos.
