That was not a "selective sound bite" that was Cruz addressing the Senate Judiciary Committee. But there is more
Asked directly, Cruz had every opportunity to state that he didnt intend for his amendment to be adopted or for the Gang of Eight bill to pass at all and in fact replied the opposite. At no point did he describe his amendment as a poison bill or procedural maneuver to derail the bill. He had every chance to say he opposed a legal status for illegal immigrants and didnt do so.
Its just that simple. Any attempt to suggest otherwise is either ill informed or dishonest.
