"Goofy Elizabeth Warren, sometimes referred to as Pocahontas, pretended to be a Native American in order to advance her career. Very racist!" Trump tweeted.
Trump has repeatedly referred to Warren as "Pocahontas," referring to Warren's past claims about her Native American heritage.
Trump and Warren targeted each other throughout the week. Warren has emerged as perhaps the Democrats' most outspoken Trump combatant and she called Trump a "thin-skinned, racist bully" after he criticized a judge with Mexican heritage.
"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." Trump tweeted in response on Friday.
Clinton also indirectly addressed the controversial remarks made by Trump on Warren in a tweet on Saturday. "When Trump goes off his staff's script he insults anyone who challenges him. Judge for his heritage, senator for hers. Rs should disavow," Clinton tweeted.
