Following Nikki Haley‘s vow to fight on with her campaign after her second consecutive defeat to Donald Trump in the GOP primary race, the former president threatened anyone donating to his Republican rival.

A day after Trump’s win in New Hampshire, he took to social media to paint Haley as “very bad for the Republican Party,” and “not the one to take on world leaders.” His words appeared to contradict statements he made in 2017 while in office, after nominating Haley to be his ambassador to the United Nations — a role that required the former South Carolina governor to work with world leaders.

Yet despite previously praising Haley as having a “track record of bringing people together regardless of background or party affiliation,” Trump resorted to name calling in his Truth Social post Wednesday night and claimed he would not accept funds from anyone donating to his opponent’s campaign. “Anybody that makes a ‘Contribution’ to Birdbrain, from this moment forth, will be permanently barred from the MAGA camp,” Trump wrote. “We don’t want them, and will not accept them, because we Put America First, and ALWAYS WILL!”

His barrage of attacks against Haley intensified after her refusal to drop out of the race amid calls from Trump and some of his allies to stand behind him. On Tuesday, Rep. Marjorie Taylor Greene (R-Ga.) told MSNBC that they would be “completely eradicating” any Republican not willing to “adapt” Trump’s policies.

Haley has said that she plans to stay in the race through March and take her bid to become the GOP presidential candidate back home to South Carolina, where she served as governor. “I don’t care how much y’all want to coronate Donald Trump,” she told Fox News. “At the end of the day, that’s not what Americans want. Americans want a choice.“

In an X/Twitter post responding to Trump’s comments on Wednesday, Haley linked to her campaign donations page and wrote: “Well in that case…donate here. Let’s Go! ❤️”
