WASHINGTON – Justice Antonin Scalia said he hasn't had a "falling out" with Chief Justice John Roberts over the Supreme Court's landmark 5-4 decision validating much of President Barack Obama's health care overhaul.

In an interview that aired Wednesday on CNN's "Piers Morgan Tonight," the justice said that, despite reports that he and Roberts had clashed, there is not a personal feud going on between the court's two leading conservatives.

"There are clashes on legal questions but not personally," Scalia said of the court.
