U.S. Sen. Elizabeth Warren, D-Massachusetts, took aim at presumptive Republican presidential nominee Donald Trump's remarks regarding a federal judge Thursday, saying that he should be ashamed of himself.

Warren, who delivered evening remarks at the American Constitution Society's annual convention in Washington, discussed what she called "a full-scale assault on the integrity of the federal judiciary and its judges," according to the speech released by her Senate office.

The Massachusetts Democrat blasted Trump's recent claims that Judge Gonzalo Curiel, who's overseeing the Trump University case, is biased against him due to his Mexican-American heritage.

Warren's criticisms of Trump marked the latest chapter in a months-long feud between the senator and the businessman.

Contending that the so-called "assault" on the judiciary is composed of two major elements -- ending centuries-old processes for appointing judges and attacking judicial nominees, potential nominees and sitting federal judges -- Warren took issue with Trump's recent comments on Curiel.

Calling the judge "one of countless American patriots who has spent decades quietly serving his country, sometimes at great risk to his own life," Warren argued that Trump, by comparison, "is a loud, nasty, thin-skinned fraud who has never risked anything for anyone and serves nobody but himself."

The Massachusetts Democrat further chastised the billionaire businessman "for using the megaphone of a presidential campaign to attack a judge's character and integrity.

"You shame yourself and you shame this great country," Warren said.

Despite blasting Trump's remarks, the senator suggested that he is not the only Republican to attack the judiciary, accusing other GOP leaders of similar conduct.

"Trump isn't a different kind of candidate. He's a Mitch McConnell kind of candidate. Exactly the kind of candidate you'd expect from a Republican Party whose 'script' for several years has been to execute a full-scale assault on the integrity of our courts ... Trump is also House Speaker Paul Ryan's kind of candidate," she said in her prepared remarks.

"Paul Ryan condemned Trump's campaign for its attacks on Judge Curiel's integrity. Great," she added. "Where's Paul Ryan's condemnation of the blockade, the intimidation, the smears, and the slime against the integrity of qualified judicial nominees and Judge (Merrick) Garland?"

Garland is President Barack Obama's nominee to succeed the late Antonin Scalia on the Supreme Court.

Warren further contended that while Trump "chose racism as his weapon," his aim is the same as that of other Republicans: "Pound the courts into submission to the rich and powerful."

The senior Massachusetts senator's remarks came amidst reports that she's planning to soon endorse presumptive Democratic presidential nominee Hillary Clinton.

She has also been named as a possible vice presidential running mate for the former first lady.

The senator called Trump a "small, insecure moneygrubber who doesn't care about anyone but himself" during a blistering speech before Democratic leaders attending the Massachusetts party convention in Lowell on Saturday.

Pointing to controversy regarding the businessman's for-profit education company as an example, she contended that Trump University was "one big 'fraudulent scheme" and Trump is "only qualified to be fraudster-in-chief."
