INDIAN WELLS, Calif. – Donald Trump is so fiercely opposed by the Koch brothers network that some donors believe the powerful group will intervene to stop the billionaire if it looks like he could win the Republican presidential nomination.

“They are always very hesitant to get involved in a primary but I think if they were going to do it this would be the time because they just hate the guy,” said a donor who attended the Koch network’s winter retreat, held over the weekend at a luxury resort near the foothills of Palm Springs’s Coachella Valley.

Both officials and donors within the powerful group hope the real estate tycoon’s White House bid dies a natural death so the group can avoid spending a penny of its $889 million 2016 cycle budget against him.
