You missed him telling Tapper “He’s pro-Mexico” and telling Dickerson on CBS “He is a member of a club or society, very strongly pro-Mexican, which is all fine. But I say he’s got bias.”
and both of those statements are completely true of course. He is a member of a Pro-Mexico organization, La Raza Lawyers of San Diego which is a chapter of the La Raza Lawyers of California which lists the council of La Raza as an affiliate
on its website and flatly states that its purpose is "to promote the interests of the Latino communities throughout the state".
