Nikki Haley wins backing from powerful Koch network as she aims to take on Donald Trump

Americans for Prosperity, the political arm of the Koch network, endorses Nikki Haley's presidential campaign, pledging support to defeat Donald Trump. The endorsement provides Haley with organizational strength and manpower, addressing her strategic liability. The Koch network, known for its conservative grassroots organization, has already communicated with six million primary voters. The endorsement deals a blow to Ron DeSantis, who struggled to emerge as the clear Trump alternative. Trump remains the frontrunner despite the endorsement.
