Former President Donald Trump penned a salty social media post Wednesday after reports emerged that his former UN ambassador Nikki Haley, who once promised she wouldn’t run against Trump, was set to do just that later this month. Haley is reportedly set to launch her 2024 presidential campaign on Feb. 15, becoming the first Republican to officially challenge Trump. “Nikki has to follow her heart, not her honor. She should definitely run!” Trump wrote on Truth Social, adding a video of the ex-South Carolina governor saying she wouldn’t run if he did.
