'These losers have fought me from 2016': Furious Trump lashes out as Koch backs opponent

Billionaire Charles Koch and the political network he finances endorsed Nikki Haley for the Republican nomination Tuesday — and Donald Trump is furious.

Taking to his Truth Social platform Wednesday, the former president hit out at the politically involved billionaire family which used to be supportive of him.

"The Globalist Koch Fake 'Network,' Americans for China Prosperity, who constantly admit that they did better in Business under President Trump than EVER BEFORE, have decided to back Nikki 'Birdbrain' Haley over Ron DeSanctimonious, a minor hit for Ron," Trump wrote.

"I was never in the running because I’m all about Making America, not the outside World, Great Again! These losers have fought me from 2016 to the present, he continued. "They are bad for our Country, and so is a very weak and ineffective Birdbrain, who still says that “President Trump was a GREAT President, I will never run against him.” She’s down 50 Points, she better start running FAST!"

A multimillion-dollar ad campaign supporting Haley is expected to follow the Koch network announcement.

“When we announced our decision to engage in our first ever Republican presidential primary, we made it clear that we’d be looking for a candidate who can turn the page on our political dysfunction — and win. It’s clear that candidate is Nikki Haley,” Emily Seidel, senior advisor to AFP Action, said in a statement.

“Nikki Haley represents a new generation of leadership and offers a bold, positive vision for our future. AFP Action is proud to be endorsing her and we will be doing everything we can to help make her the next President of the United States.”
