Five candidates for the US Republican Party's presidential nomination for the country's 2016 election went to a donor retreat held by US billionaires Charles and David Koch.
US Republican Party candidate, and also a billionaire, Donald Trump was not invited to the retreat, where candidates present themselves to vie for funding for their political campaigns.
"He was not invited, we also know that the 'Koch network' is trying to freeze him out, they are not happy about his candidacy," Tarini Parti of Politico told Radio Sputnik's BradCast.
The meetings are held twice a year by the politically influential billionaires, and have recently become less secret and more opened to reporters.
I wish good luck to all of the Republican candidates that traveled to California to beg for money etc. from the Koch Brothers. Puppets?
