Regardless of your position on the subject (I personally think Ted Cruz' arguments on the first and fourth amendments is weak in this context), it makes me smile when a dusty old senator like Diane Feinstein gets defensive and annoyed when someone has the nerve to question her. Doesn't Ted Cruz know who she is!? Yes. Yes he does. New blood in DC is a good thing.
And poor little Diane Feinstein later said she felt patronized. You mean like how you patronize and lecture Americans about their guns?
And that wasn't the first time the Ewok, Wolf Blitzer, has done a segment on Ted Cruz upsetting the herd. Here's the Ewok lecturing Ted Cruz when Cruz first got to DC.
