Graham defends Trump's 'Pocahontas' insult against Warren
"I thought it was funny," Graham told reporters, asked if he thought the comparison is racist. "I think what he said about the judge was racist. When you're talking about a politician, you've got to be able to take a joke." 
Trump, the presumptive GOP presidential nominee, has been under growing criticism from Graham and other Republicans this week for saying Judge Gonzalo Curiel, who is overseeing cases against Trump University, isn't being fair because of his Hispanic heritage.  
The South Carolina Republican's comments come after Trump knocked Warren Friday morning, saying "Pocahontas is at it again! Goofy Elizabeth Warren, one of the least productive U.S. Senators, has a nasty mouth. Hope she is V.P. choice.”
Warren has stepped up her criticism of Trump, including in a speech Thursday night where she called him a "loud, nasty, thin-skinned fraud." 
Graham added Friday that Warren had called Trump "small-minded, weak, racist. That's pretty funny." 
"Now the Pocahontas thing. You know she started all of this," Graham told reporters. "I don't refer to her as Pocahontas. I can see why she would be offended, absolutely. ...But given this contest, if this bothers you, you need to get out of politics."
Trump has repeatedly tagged Warren with the nickname, referring to a controversy over Warren's claim that she has Native American heritage. 
Graham isn't supporting Trump and has warned that his controversial comments about Curiel could lead to Republicans dropping their endorsements.
