Ex-Trump staffer lashes out at ‘Kuck Brothers’ after the billionaires denounce president's trade war

The open battle between the White House and the billionaire Koch brothers escalated further on Tuesday when former Donald Trump campaign advisor Sam Nunberg insulted the billionaire heirs.

"The Kuck Brothers (sic) better check themselves before they wreck themselves & get with the Donald Trump White House - punks," Nunberg tweeted.

The alt-right has referred to their Republican Party enemies as "cuckservatives," which is a portmanteau of a shortened version of the word "cuckold" and "conservative."

In 2016, GQ explained, "the word 'cuck' resonates with white nationalists who feel as though their country has been taken away from them, and not enough had been done by the cuckservative establishment conservative party to protect it. 'Cuck' is a concept borne out of insecurity: a fear that one is inadequate, sexually or otherwise, and that inadequacy will lead to the loss of the things that are important to him."

"If one’s insults represent their own fears, those who call others a cuck do so in the desperate hope that shreds of their own masculine and racial prominence can be protected," GQ added.

David and Charles Koch have publicly said that President Donald Trump is doing "long-term damage" to America.

Charles Koch has said he doesn't care if Democrats take back the House of Representatives in 2018.

Also on Tuesday, President Donald Trump lashed out at the Koch brothers.

The billionaire brothers have said they intend to spend $400 million dollars in the 2018 midterms.
