A three-judge federal appeals panel comprised of two Obama nominees and a Clinton nominee will hear arguments later this morning in two lawsuits challenging the constitutionality of the national health care law. The makeup of the U.S. Fourth Circuit of Appeals panel is crucial, because in lower court rulings so far, Democratic judges have upheld the law while Republican judges have declared it unconstitutional. The judges on the panel will be Obama nominees James A. Wynn, Jr and Andre M. Davis, who will sit on the panel along with Clinton nominee Diana Gribbon Motz.
