Despite his decisive win in the New Hampshire primary, former President Donald Trump spent the evening venting frustration over Nikki Haley's decision not to concede and drop out of the GOP presidential race. Trump expressed his irritation both publicly by criticizing Haley's speech and attire online and privately by instructing his aides to intensify their attacks on her. This behavior was a stark contrast to his more cheerful demeanor following the Iowa caucuses, showcasing a shift in his response from congratulatory to vengeful.
