Donald Trump suggested that a lawsuit over his controversial Trump University has benefited from the Hispanic ethnicity of the "very hostile" judge presiding over the case.

The remarks during an Arkansas campaign rally comes a few days after Sen. Marco Rubio brought up the legal troubles of Trump University, the billoinaire's now-defunct real estate college, during a debate. Several former students in California filed a class action lawsuit saying the school was a fraud.

Rubio said students paid $36,000 to go to "a fake school."

Trump said at the rally that the lawsuit should have been thrown out because of a video of a student who said that she liked the school.

But it was not, Trump said, due to "tremendous hostility" towards him by the judge.

"I believe he happens to be Spanish, which is fine," Trump said. "He's Hispanic, which is fine."

Trump said his lawyers have not asked the judge to recuse himself, but might do so. The GOP front-runner did not say specifically why the judge should reccuse himself, leaving the impression he believes a Hispanic judge cannot objectively consider his case.

The real estate mogul has based his campaign on combating illegal immigration, saying he would build a wall and deport millions of illegals.

Trump added that a "sleaze-bag law firm" that sues everybody was behind the suit. He added that he didn't settle the lawsuit because he doesn't believe in it.

"I would rather spend a lot more money and fight," he said, which drew applause from the raucous crowd.

Trump also went after New York Attorney General Eric Schneiderman, who sued Trump in 2013 claiming the university was a fraud and didn't teach consumers anything useful.

"More than 5,000 people across the country who paid Donald Trump $40 million to teach them his hard sell tactics got a hard lesson in bait-and-switch," Schneiderman said in a statement.

Trump said Schneiderman was "probably not electable in New York."

Schneiderman said in a statement Saturday that he will not "engage in a debate about ongoing litigation. But he there is no place in this process for racial demagoguery directed at respected members of the judiciary."
