Trump's comments were not made in response to comments Mario Obledo made on the Ray Briem talk show in 1998. You can be certain of that.   Mario Obledo's comments are interesting nonetheless if you understand the context.  When American's of a particular ethnic group are repeatedly told to go back to a country they are not from, they get angry.  If the message comes from other ethnic group(s) that are not indigenous, then the logical response might be to tell those people to go back to countries of their ethnic heritage.  This is not productive discourse.  But this banter has nothing to do with Judge Curiel.
