WATCH: Elizabeth Warren Attacks Donald Trump in Speech

Elizabeth Warren set in motion her latest attack on Donald Trump Thursday night.

The senator called the presumptive Republican nominee a “loud, nasty, thin-skinned fraud,” as she addressed the American Constitution Society’s national convention in Washington.

In a succession of insults, she called Trump a “racist bully” who has “never risked anything for anyone and who serves no one but himself.”

She highlighted Trump’s description of US District Court Judge Gonzalo Curiel as biased because of his Mexican heritage.

Not only did Warren tear into Trump, but the entire Republican party.

“Donald Trump chose racism as his weapon,” she said. “But his aim is exactly the same as the rest of the Republicans: to pound the courts into submission for the rich and the powerful.”

Warren’s remarks are the latest of many she has made against Trump. Warren and Trump have been involved in rhetorical battles before, often on Twitter.

On Thursday, Warren also endorsed former Secretary of State Hillary Clinton for president.

Warren gave her endorsement in an interview with the Boston Globe on Thursday.

“I’m ready,” Warren said, according to the Globe. “I’m ready to jump in this fight and make sure that Hillary Clinton is the next president of the United States and be sure that Donald Trump gets nowhere near the White House.”

In an interview with MSNBC’s Rachel Maddow Thursday night, Warren explained her endorsement and why she did not endorse a candidate during the Democratic primary.

Warren went on to describe the work of Bernie Sanders as “powerfully important.” However, she also said it’s time for Sanders to unite behind Clinton.
