Network founded by Koch brothers says it will stop spending on Nikki Haley's presidential campaign

Americans for Prosperity Action, a libertarian conservative political policy network founded by the billionaire Koch brothers, announced on Sunday that it will no longer spend on Nikki Haley's presidential campaign. 

The cut comes after Haley lost the Republican primary in her home state of South Carolina on Saturday to former President Donald Trump by 20 points. 

"Nikki Haley has shown us again and again that we made the right decision in supporting her candidacy and she continues to have our strong endorsement," AFP CEO Emily Seidel wrote in an email to staff, first reported by Politico.
