Sam Nunberg, a former political adviser for Donald Trump, has decided to support Ted Cruz for president, Politico reported.

“Cruz is a Reagan Conservative. Donald Trump does not have a coherent political ideology — if anything, I would describe him as a Chris Christie Republican,” Nunberg said in a statement first published by Politico on Monday.

Trump fired his Jewish political advisor last August after Business Insider revealed past racially-charged Facebook posts. Nunberg allegedly wrote racially-charged and disparaging political posts dating back to 2007, including one calling Rev. Al Sharpton’s daughter a “N—!” and President Barack Obama a “Socialist Marxist Islamo Fascist Nazi Appeaser.”

Nunberg denied he wrote the posts. “Anything that was posted under my name does not mean I posted it,” he told CNN at the time. “I would also point out that all of these things were done before Mr. Trump’s campaign, if I even did them — which I deny.”
