"Duck Dynasty" star Phil Robertson preached to the Republican Leadership Conference on Thursday, telling the GOP to "get godly" and referring to statements from the White House as "evil."

"You can't be right for America if you're wrong with God," Robertson said, according to The Times-Picayune. And, if "you want to turn the Republican party around, get godly," he told the crowd.

Robertson, a late addition to the conference schedule, "spoke in a somewhat meandering fashion for about half an hour," The Washington Post reported. He said he was surprised to be asked to speak, but he rallied Republicans as he touched on guns and his opposition to the separation of church and state.

In regard to President Barack Obama, he said: “We’re up against evil like I’ve never seen in my life. I’m sitting there and I’m thinking, ‘What’s coming out of the White House?' The only thing I can tell you folks is it’s just downright embarrassing.”

Robertson has been called out for racist comments in the past, but on Thursday he called for racial unity.

“There’s one race on this planet, and it’s called the human race,” Robertson added, according to The New Orleans Advocate. “Therefore you have no right to color-code anyone. We’re all the same family.”

After the speech, Robertson told Fox News' Sean Hannity that recent controversy over his comments about homosexuality "goes with the territory" of spreading Christianity.

“I would never judge or condemn anyone. … I just give them the Good News,” Robertson said. “My message is always the same -- ‘God loves you and sent Jesus to die for you.’”
