Story highlights "It is highly offensive as a Hispanic. What he is doing is wagging the dog," Navarro said

Navarro said she doesn't currently have a candidate to support

Washington (CNN) Republican strategist and CNN contributor Ana Navarro excoriated Donald Trump on Friday for attacking a judge with Mexican heritage who is presiding over a lawsuit against Trump University.

Speaking to CNN's Jake Tapper on Friday , Trump doubled down on his criticism that U.S. District Court Judge Gonzalo Curiel was biased against him because of his tough policy proposals against Mexico and illegal immigration.

Curiel last week ordered parts of internal documents, including "playbooks" regarding running the enterprise, to be released as part of a lawsuit against Trump University in response to a request by The Washington Post.

Navarro said the presumptive GOP presidential nominee was merely trying to distract from misconduct by the now-defunct school.

"It is highly offensive as a Hispanic. What he is doing is wagging the dog," Navarro told CNN's Wolf Blitzer on "The Situation Room." "How dare he.

He is just as American as Donald Trump."
