MYRTLE BEACH - Sen. Ted Cruz is jokingly proposing Duck Dynasty patriarch Phil Robertson for a top diplomatic post.

"Imagine just for a moment: Phil Robertson, ambassador to the United Nations," the Texas senator said at a Friday morning rally in Myrtle Beach, South Carolina. "How much would you pay to see the Russian ambassador's face when Phil says: 'What is wrong with you people?"

Cruz is campaigning Friday with the bearded reality television star on the eve of the South Carolina Republican presidential primary. Robertson is a cult hero among social conservatives for his unvarnished critiques of modern, secular society.

Speaking ahead of Cruz, Robertson urged voters to "rise up as the sons and daughters of God" and put "a staunch, Bible-belieiving, Jesus-loving, Godly man" in the White House.
