Nikki Haley's Iowa Surge and New Hampshire Poll Gains Spark GOP Rivalries Ahead of Caucus

At an Iowa town hall, GOP candidate Nikki Haley discussed her campaign strategy to challenge Donald Trump, addressed past controversial remarks on slavery, and criticized Trump's "chaos." She emphasized mental health over gun control in response to a recent school shooting and defended her potential to be the "right" female president. Haley's comments on Trump's legal issues and her own political maneuvers were met with criticism from Trump allies and the Democratic National Committee.
