"The San Diego La Raza Lawyers Association (SDLRLA) is a local diversity bar association whose reputation among the San Diego legal community is highly regarded. Our focus is “to advance the cause of equality, empowerment and justice for Latino attorneys and the Latino community in San Diego County through service and advocacy. We are dedicated to promoting diversity on both the bench and bar…” (http://sdlrla.com/about/mission-statement/)."
And among their roster of lawyers, their case history is full of (and I'm not going to repeat this again) defending hispanic individuals accused of illegal immigration, among other things. Trump is completely correct to question the judge's allegiances; not based on his race, but based on this La Raza affiliation.

By the way, you guys talk about Trump being a "puppet." Have a look at this:

Bernie Sanders makes one of his major campaign points an adversity to Wall Street... and then proceeds to support a candidate heavily endorsed by Wall Street, Hillary Clinton.
Say what you want about Cruz, Rubio and Trump, but they have the courage to say "no, I won't support this other Republican because I disagree with him." The cronyism runs deeper in the Democratic party than the Republican one it seems.
