Diving Deeper:

Joining Jon Karl on ABC's "This Week," Nikki Haley, the former U.S. Ambassador to the United Nations refused to confirm whether she would support Donald Trump if he wins the GOP nomination. This comes as a surprise to many, as Haley had previously pledged to back the eventual Republican nominee, a pledge she made in order to participate in the GOP debates. However, Haley's recent comments suggest a shift in her stance towards Trump, with the presidential hopeful stating, "I'm running against him because I don't think he should be president."

Over the past few weeks, Haley has ramped up her criticism of Trump, expressing concerns about his potential impact on the NATO alliance and the Republican National Committee. During a recent interview with ABC's "This Week", Haley voiced her fears that Trump could threaten to upend the NATO alliance, stating, "I'm worried about a lot of things if Trump is reelected. That is one of them." She also criticized Trump for endorsing his daughter-in-law Lara Trump to serve as a co-chair of the Republican National Committee, expressing concerns that the RNC could become a "piggy bank for Trump's legal fees."

Despite her efforts, Haley is currently trailing Trump in the polls by a significant margin. The next stop in the GOP nominating calendar is South Carolina, Haley's home state where she served as governor from 2011 to 2017. However, Haley is also trailing Trump in every poll there, with the contest slated for Feb. 24. As the race continues, it remains to be seen whether Haley's recent comments and criticisms of Trump will have an impact on her campaign and the overall GOP nomination.
