The loss of Justice Antonin Scalia is a tremendous loss for the Supreme Court and for America. He was a principled Constitutionalist that provided an excellent model for how a Supreme Court Justice should evaluate a case and interpret the original intent of the law.
Senator Lankford believes his passing leaves a significant vacancy and therefore a monumental decision that will make a profound impact on the courts and many impactful decisions for decades.
The Constitution gives the White House and the Senate a 50-50 equal responsibility in the process of confirming a Supreme Court Justice.
As a U.S. Senator, Lankford has the responsibility to fulfill his Constitutional role of 'advice & consent' on a Justice nomination. Senator Lankford's standard for a Supreme Court Justice is very high and does not change based on which President nominates her or him.
