Donald Trump's mug shot has apparently brought a financial boon for his presidential campaign, raising over $7.1 million since he was booked on racketeering and conspiracy charges last week.

The campaign had quickly embraced the scowling image of the former president – the first mug shot of a serving or former U.S. leader – as the symbol of his bid to take back the White House in 2024.

"Close to $20m raised in the last 3 weeks, coinciding with the DC indictment and Atlanta mugshot," campaign spokesman Steven Cheung confirmed to Agence France-Presse (AFP) Sunday.

"$7.1 million since Thursday (Atlanta mugshot). $4.18 million yesterday alone, the highest-grossing day of the entire campaign," he continued.

"Organic money has skyrocketed, especially after President Trump tweeted out the picture along with the website."

AFP could not independently verify the claims.

On X, formerly known as Twitter, Cheung urged U.S. media to "Please continue to show it," and included what he said was a high-resolution version of the image.

T-shirts, mugs, stickers and beverage coolers bearing the mug shot – arguably now the most famous in U.S. history – were put out by Trump's team within hours of the photo's release.

Notably absent from the merchandise is the local sheriff's badge watermark that appeared in the image released by authorities.

While such a photo would surely sink any other political candidate, for 77-year-old Trump it plays into his narrative of a defiant, heroic victim.

Marketing experts have even likened it to the "Hope" poster from Barack Obama's successful 2008 presidential campaign.

Democrats have also used it, however, suggesting that it shows no one is above the law.

As for Biden, he shrugged it off in comments to reporters on Friday, quipping: "I did see it on television. Handsome guy."
