Presidential candidate Donald Trump went after his Republican rivals who flew to a seminar held by industrialists Charles Koch and David Koch to “beg for money.”

I wish good luck to all of the Republican candidates that traveled to California to beg for money etc. from the Koch Brothers. Puppets? — Donald J. Trump (@realDonaldTrump) August 2, 2015

“Puppets?” he asked in a tweet.

Florida Sen. Marco Rubio, Texas Sen. Ted Cruz, former Florida governor Jeb Bush, Carly Fiorina and Wisconsin Gov. Scott Walker all appeared in front of an invitation-only gathering of some 450 wealthy, conservative donors aligned with the brothers. Trump is not a favorite of the Kochs, who have allegedly made reducing the size of government and overhauling the criminal justice system among their priorities.

Trump has been focusing relentlessly on illegal immigration and it doesn’t seem he is wanted in the Koch Brothers circles but then that suits Trump’s supporters just fine.

Check out how they responded to the brothers’ event:
