Chris Christie is generally viewed as an Establishment alternative for the GOP presidential nomination, but on Wednesday he sounded hostile toward the Republican Party’s insiders.

Appearing on “The Laura Ingraham Show,” the New Jersey governor hit Florida Sen. Marco Rubio on immigration and House Speaker Paul Ryan, R-Wis., on the budget.

Christie sided with outsider Texas Sen. Ted Cruz’s attack on Rubio — lodged during Tuesday’s Republican presidential debate — over the Florida senator’s participation in the Senate Gang of Eight. The “gang” pushed an immigration reform measure that would have granted eventual citizenship to millions of illegal immigrants.

“That was a very interesting interchange,” Christie said. “I think it showed people a lot of things about Rubio and his record on immigration that they didn’t know before.”

Christie disagreed with former Florida Gov. Jeb Bush’s debate line about front-runner Donald Trump being a “chaos candidate” who has not offered serious proposals to address America’s problems.

“He looks like a serious candidate to me,” he said. “Donald’s giving voice to the real concerns of a lot of Americans. And those concerns need to be heard and acknowledged and addressed by anybody who seriously believes they can be a candidate for president of the United States for our party and defeat Hillary Clinton in the fall.”

Christie said the party needs to start listening to voters.

“They’re not just whispering to us,” he said. “Their yelling to us about what they want our priorities to be.”

Christie also blasted a spending deal announced Tuesday night by the speaker’s office. Among other things, the $1.15-trillion bill would fund President Obama’s plan to resettle 10,000 Syrian refugees in the United States by the end of September.

“It seems contrary to everything we stand for as Republicans,” Christie said.
