(CNN) A spokeswoman for Donald Trump on Monday continued a line of criticism launched by Trump about a California judge who is overseeing a fraud case against him. She also suggested that the judge's Hispanic heritage and membership in a Latino lawyers association would affect his ability to judge the case.

The criticism comes days after Trump himself said at a rally that U.S. District Court Judge Gonzalo Curiel "happens to be, we believe, Mexican," criticizing him for scheduling a trial for the suit against Trump University in November.

Appearing on CNN's "New Day," spokeswoman Katrina Pierson criticized Curiel for being a member of the La Raza Lawyer's Association, which is a leading Latino lawyers group in California. Curiel is a member of the organization's San Diego chapter.

"I think what's really interesting about this particular judge -- as Mr. Trump refers to him as a 'Trump hater' -- is he even mentions on his judicial questionnaire that he was a La Raza Lawyers Association member," Pierson said, apparently referring to the questionnaire Curiel filled out when his confirmation was being considered by the Senate. "This is an organization that has been out there organizing anti-Trump protesters with the Mexican flags -- they are pushing it. The signs have been very apparent. And so Mr. Trump is just stating the obvious."

CNN has reached out to the La Raza Lawyers Association's national office and the San Diego chapter, but calls were not immediately returned.
