Vice President Joe Biden, Elizabeth Warren Tear Into Trump

— -- Sen. Elizabeth Warren launched into her latest attack on Donald Trump Thursday night -- specifically over his comments about the judge overseeing two fraud cases against Trump University -- calling the presumptive GOP presidential nominee a "loud, nasty, thin-skinned fraud," in remarks at the American Constitution Society’s national convention in Washington, D.C., Thursday night.

"Donald Trump is a loud, nasty, thin-skinned fraud who has never risked anything for anyone and who serves no one but himself," Warren said at the event, where Vice President Joe Biden also spoke.

Biden echoed Warren's remarks at the event, calling Trump's conduct "reprehensible," "racist" and that the situation "smacks of authoritarianism."

“A presidential candidate who publicly attacks a sitting federal judge who ruled in a way that was against his own economic interests cannot be trusted to respect the independence of the judiciary as president,” Biden said.

Warren's remarks come on the same day that she also endorsed Hillary Clinton for president, in an interview with Rachel Maddow on MSNBC. Warren, who declined to mount a 2016 White House bid of her own last year after the urging of supporters, has been floated as a prospective vice presidential pick to Clinton.

"Trump is picking on someone who is ethically bound not to defend himself – exactly what you’d expect from a thin-skinned, racist bully," Warren said, defending Judge Curiel against Trump Thursday night.

Noting that Trump has said Judge Curiel should be ashamed of himself before quickly, Warren said it is Trump who should be ashamed and called the presumptive GOP nominee "a total disgrace."

"No, Donald – you should be ashamed of yourself, ashamed," Warren said. "Ashamed for using the megaphone of a Presidential campaign to attack a judge’s character and integrity simply because you think you have some God-given right to steal people’s money and get away with it. You shame yourself and you shame this great country."

"Race-baiting a judge who spent years defending America from the terror of murderers and drug traffickers simply because long ago his family came to America from somewhere else. You, Donald Trump, are a total disgrace," she said.

The Massachusetts senator also tied Trump directly to Senate Majority Leader Mitch McConnell and House Speaker Paul Ryan by making the case that Trump is only taking a page from their playbooks.

"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," Warren will say, in accusing McConnell of blocking judicial nominations.

"Trump is also House Speaker Paul Ryan's kind of candidate," she will say. "Paul Ryan condemned Trump’s campaign for its attacks on Judge Curiel's integrity. Great. Where's Paul Ryan's condemnation of the blockade, the intimidation, the smears and the slime against the integrity of qualified judicial nominees and [Supreme Court nominee] Judge [Merrick] Garland?"

"Donald Trump chose racism as his weapon, but his aim is exactly the same as the rest of the Republicans: Pound the courts into submission to the rich and powerful," Warren said.

"We will not allow a small, insecure, thin-skinned, wannabe tyrant or his allies in the Senate to destroy the rule of law in the United States of America,"

Warren's remarks are only the latest addition to the senator’s many attacks on Trump. She has been outspoken in her criticism of the presumptive Republican nominee in recent months, often using Twitter to unleash social media rants against him.

Trump has similarly used Twitter to bash Warren, calling her "goofy Elizabeth Warren" and attempting to mock her Native American heritage by calling her "Pocahontas."
