Donald Trump ramped up his attacks on Nikki Haley Wednesday by threatening to shun anyone who donated to her campaign.

“Anybody that makes a ‘contribution’ to Birdbrain, from this moment forth, will be permanently barred from the MAGA camp,” he wrote on Truth Social. “We don’t want them, and will not accept them.”

Haley's defiant tone during her speech after losing to Trump in the New Hampshire primary apparently drew the ire of the former president, as well as her saying he's "not as sharp" as he once was in light of recent gaffes and rambling speeches he's made.

But Trump's threat to Haley's donors seems to have had the opposite effect from what he hoped, with people taking to X to declare that Trump's threat inspired them to donate to Haley.

Others accused Trump of using "mob boss" tactics.

"This is how the Mafia and cartels operate," journalist David Lazerus wrote.

"So… Trump has alienated Independents. He’s alienated DeSantis supporters. Now he’s alienating Haley supporters. Is there no one with balls enough on his team to tell him the whole ‘mob boss’ routine is not a winning strategy?" X user and "Reagan/DeSantis Republican" The Might Quinn wrote.

"Black-listing donors in a race Democrats are going to outspend Republicans by hundreds of millions. Great strategy," wrote conservative blogger Bonchie.

"Seems like a good time to send Nikki a modest contribution," wrote The Bulwark's editor Bill Kristol.

"Please let the Trump team know that I donated to Haley," wrote another X user.

"I just donated to Nikki Haley. You should, too — and so should your family. Proud to be “permanently barred” from Trumpism. Feels nice. Try it!" wrote conservative lawyer Heath Mayo.
