The Associated Press reports:
Inside the West Wing and in conversations with outside allies, Trump has been workshopping new attempts to imprint his new adversaries with lasting labels, according to two people on whom the president has tested out the nicknames.
They spoke on condition of anonymity to discuss private conversations with the president. He is also testing out lines of attack in public rallies, exploring vulnerabilities he could use against them should they advance to the general election.
No candidate has drawn more commentary and criticism from Trump than Sen. Warren, the liberal Massachusetts Democrat. Warren’s past claims of Native American heritage prompted Trump to brand her “Pocahontas” and he has shown no qualms about deploying racially charged barbs harking back to some of the nation’s darkest abuses.
