Haley, who like Trump is weighing a 2024 bid, has thrown her support behind GOP Rep. NANCY MACE. The former governor held a Friday afternoon fundraiser for the freshman congresswoman at the Harbour Club in Charleston that netted over $250,000. But Trump is gunning for Mace — who sharply criticized him following the Jan. 6 Capitol riot — and will likely unload on her at tonight’s rally. He’s backing Mace primary challenger KATIE ARRINGTON, who’s expected to be on hand and is listed as the co-chair of a pre-rally fundraising reception. See the invite here

“Big rally in South Carolina this weekend,” Trump said Friday. “Will be honoring Katie Arrington, who is running against the absolutely horrendous Nancy Mace.”

Mulvaney, a former South Carolina congressman who served more than a year as White House acting chief of staff, said in a text message he believes Trump “simply got bad advice in this race.” He noted that Arrington, after prevailing in the Republican primary, lost her 2018 bid for the conservative-leaning House seat to a Democrat.
