Former President Trump said anyone who contributes to his opponent's campaign will be barred from the "Make America Great Again" MAGA community - but former United Nations Ambassador Nikki Haley quickly used the comment to her campaign's advantage.

In a TruthSocial post Wednesday, Trump hit Haley with insults ranging from "Birdbrain" to saying "she was average at best" when serving in his administration.

"Nikki "Birdbrain" Haley is very bad for the Republican Party and, indeed, our Country. Her False Statements, Derogatory Comments, and Humiliating Public Loss, is demeaning to True American Patriots," Trump wrote in a lengthy post.

The former president then went on to write that anyone who contributes to Haley's campaign "will be permanently barred from the MAGA camp."

"When I ran for Office and won, I noticed that the losing Candidate’s "Donors" would immediately come to me, and want to "help out." This is standard in Politics, but no longer with me," Trump wrote. "Anybody that makes a "Contribution" to Birdbrain, from this moment forth, will be permanently barred from the MAGA camp. We don’t want them, and will not accept them, because we Put America First, and ALWAYS WILL!"

Rather than stay silent, Haley reposted Trump's message on X with a link to donate to her campaign.

Several X, formerly known as Twitter, users responded to Haley's post with screenshots showing their donations to her campaign. Other X users mocked her for still staying in the GOP primary race.

Trump took aim at Haley Thursday morning on Truth Social, saying he "heard BIRDBRAIN [Haley] totally ‘bombed’ last night in South Carolina," referring to her rally in North Charleston Wednesday evening.

"Why the surprise, she just bombed in Iowa and New Hampshire in a very big way, and lost both States," Trump continued. "She also just lost Nevada because she saw the Polls and decided to take a pass on this Caucus State. 100% Trump!"
