Nikki Haley says Trump feels 'threatened' and is lashing out, believes she'll pick up DeSantis voters

Nikki Haley believes she can attract some of Gov. Ron DeSantis' supporters even though the Florida Republican endorsed former President Trump after withdrawing from the race for the GOP nomination.

"I think his supporters are up for grabs," the former U.N. ambassador told Steve Doocy in an exclusive "Fox & Friends" interview that aired Monday.

"Think about it. His supporters love America and they wanted a new generational leader. We give them that."

DeSantis suspended his struggling bid for the nomination on Sunday after coming in second in the Iowa caucuses, leaving Haley as the only alternative to former President Trump left in the race.

Ahead of Tuesday's New Hampshire primary, DeSantis failed to reach 10% of the expected vote. Trump, meanwhile, still holds a massive lead over Haley in the race, with many speculating DeSantis' endorsement could lead his supporters to gravitate toward Trump in the Granite State and beyond.

Haley said she "know[s]" she's "getting to" Trump at this point in the race, pointing to his attacks slamming her as a "losing candidate who puts America last."

The former South Carolina governor has support from many independent voters, including some Doocy questioned at campaign
