Obama isn't the first to criticize SCOTUS:
Has Any President Ever Criticized the Supreme Court During an Oral State of the Union Address?
Yes. Presidents have mentioned the “Supreme Court” in 10 SOTUs, nine of them oral. Two more referred to the “judicial branch” (also all oral). Five more mention “the judiciary” ( all oral), some in the same speech using “the Supreme Court. Several of these have called for legislation to address a law that has been invalidated by the Supreme Court (Harding, Eisenhower, Carter). Roosevelt explicitly criticized the Supreme Court as did Reagan.
