He said that Gay marriage is the law of the land? Could the congress repeal the law the courts made?
Congress sets law, the Supreme Court reviews to meet Constitutional standards when a case is presented....The Court does not set law....
If he answered no, he would have been required to recuse himself when the case came before the court....
Not to mention he would never be confirmed.
So effectively, by stating he will follow the law when considering a previous ruling, he now is open to consider new cases.....
These kind of questions of Supreme Court nominees are simply trap questions....to either bury their appointment or remove them from considering a case....
