"Billionaire-backed Koch network endorses Nikki Haley for president, leading the charge against Biden and Trump"

The Koch network, largely financed by billionaire Charles Koch, has endorsed former U.S. ambassador to the United Nations Nikki Haley for president, signaling a challenge to former President Donald Trump in the Republican primary. Americans for Prosperity Action, the Koch-backed super PAC, has already spent millions of dollars criticizing Trump and is prepared to deploy its massive resources to support Haley. The endorsement comes as a blow to Florida Governor Ron DeSantis, who received AFP's endorsement just a year ago. The Koch network has had a complex relationship with Trump, scoring policy victories but also clashing on issues like trade.
