Fox News host Tucker Carlson suggested on Sunday that Republican presidential candidate Marco Rubio seek the endorsement of conservative columnist Ann Coulter after she launched a racial attack on the candidate's Latino father.

Following Donald Trump's win in the South Carolina Republican Primary on Saturday, Coulter celebrated by taking a jab at Rubio's Cuban heritage.

"Could someone please have Marco's bartender dad make me a mojito?" she wrote. "I'd like to toast Trump's amazing victory!"

Coulter also recently accused Rubio of running an "anti-white men campaign."

On the Sunday edition of Fox & Friends, Carson speculated that former Republican presidential nominee Mitt Romney's endorsement of Rubio would not help him with conservative voters.

"Sure, he can get that side, great -- nothing against Romney at all, of course," Carlson opined. "But he's already won that part of the party."

"Shouldn't Rubio be looking for the Ann Coulter endorsement this morning?" he added.
