Congressman Vela wrote a letter to Donald Trump excoriating him for his racist views:
I would like to end this letter in a more diplomatic fashion, but I think that you, of all people, understand why I cannot. I will not presume to speak on behalf of every American of Mexican descent, for every undocumented worker born in Mexico who is contributing to our country every day or, for that matter, every decent citizen in Mexico. But, I am sure that many of these individuals would agree with me when I say: ‘Mr. Trump, you’re a racist and you can take your border wall and shove it up your ass.’
To preempt the Donald’s predictably racist backlash, he establishes his own background:
Before you dismiss me as just another “Mexican,” let me point out that my great-great grandfather came to this country in 1857, well before your own grandfather. His grandchildren (my grandfather and his brothers) all served our country in World War I and World War II. His great-grandson, my father, served in the U.S. Army and, coincidentally, was one of the first “Mexican” federal judges ever appointed to the federal bench.
Linkey contains the entire letter.
