Sen. Elizabeth Warren, D-Mass., slammed President Trump Monday for being "truly disgusting" after he called her "Pocahontas" during a White House ceremony held to commemorate Native Americans who fought in World War II.

"This was an event that was to honor war heroes, to honor people who had put it all on the line for America and America's allies," Warren told Bloomberg.

"And that Donald Trump has to get in a racist slur is truly disgusting," she continued.

Warren added Trump's political attacks would not silence her opposition to his legislative agenda.

"He thinks somehow it's going to make me shut up," she said. "It hasn't worked in the past, it's not going to work in the future."

Warren, who was instrumental in the establishment of the Consumer Financial Protection Bureau in 2011, also weighed in on the controversy surrounding the agency's leadership.

She said she stands behind acting director Leandra English, who was appointed by outgoing director Richard Cordray on Friday, despite Trump simultaneously nominating White House budget director Mick Mulvaney to the post.

The Dodd-Frank Wall Street Reform and Consumer Protection Act states a director can name a successor while the Senate works to confirm a presidential pick.

"She hasn't been there in a political position, she's been there on behalf of the American people," Warren said of English, whom she met with on Monday. "No one needs to appoint her."
