Sen. Elizabeth Warren (D-Mass.) plans to excoriate Senate Republicans and presumptive GOP presidential nominee Donald Trump for what she called a "full-scale assault" on the U.S. judicial system.

Warren on Thursday will criticize Republicans for blocking President Barack Obama's judicial nominees and for "viciously attacking" those picks and sitting judges "at the first sign that they might put the rule of law above devotion to the rich and powerful,” according to advance excerpts of a speech she plans to make at the national convention of the American Constitution Society, a progressive legal organization.

"Powerful interests are now launching a full-scale assault on the integrity of the federal judiciary and its judges," Warren says in the prepared remarks provided by her office.

Warren plans to take Trump to task over his racist claim that Gonzalo Curiel, the federal judge handling two lawsuits against Trump University, is biased against him because of his Mexican heritage.

“Judge Curiel is one of countless American patriots who has spent decades quietly serving his country, sometimes at great risk to his own life," Warren says. "Donald Trump is a loud, nasty, thin-skinned fraud who has never risked anything for anyone and serves nobody but himself. And that is just one of the many reasons why he will never be president of the United States."

Warren will link Trump to Senate Majority Leader Mitch McConnell (R-Ky.) and House Speaker Paul Ryan (R-Wis.), arguing that their rhetoric of obstruction allowed Trump's rise within the GOP.

"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 says. "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's speech comes after she accused McConnell and his Republican Senate colleagues of "petty" and "absurd" obstruction tactics. She cited her report from earlier in the week detailing how the GOP has blocked Obama's judicial picks.

"The view of Senate Republicans seems to be pretty simple — if government isn’t working for them, for their rich friends or for their right-wing allies, then Senate Republicans won’t let it work for anyone," Warren said on the Senate floor Wednesday.

Warren has emerged as one of the Democratic Party's most effective Trump critics, repeatedly admonishing him for his offensive remarks and rhetoric. Her fiery attacks haven't gone unnoticed by Hillary Clinton's campaign, and there have been suggestions that Clinton consider Warren as a potential running mate in the general election. As The Huffington Post's Zach Carter and Ryan Grim reported Wednesday, Senate Minority Leader Harry Reid (D-Nev.) is on board with that idea.

Warren reportedly plans to endorse Clinton soon.

Editor’s note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims — 1.6 billion members of an entire religion — from entering the U.S.
