U.S. Supreme Court Justice Antonin Scalia was found dead Saturday, CBS News has confirmed. A spokesperson for the U.S. Marshals said he appeared to die of natural causes.
According to the San Antonio News-Express, which was first to report his death, Scalia was found dead in his room at a West Texas resort.
Scalia, 79, was one of the staunchest conservative members of the court. He was nominated in 1986 by President Ronald Reagan and is the longest-serving member on the court.
He championed the philosophy of "orginalism," meaning he interprets the Constitution according to what he believes the original authors intended over 200 years ago.
In a 2008 interview with "60 Minutes," he told correspondent Lesley Stahl that he believes the Constitution is an "enduring" document he wants to defend.

"It's what did the words mean to the people who ratified the Bill of Rights or who ratified the Constitution," Scalia said.
"But you do admit that values change? We do adapt. We move," Stahl asked.
"That's fine," he answered. "And so do laws change. Because values change, legislatures abolish the death penalty, permit same-sex marriage if they want, abolish laws against homosexual conduct. That's how the change in a society occurs. Society doesn't change through a Constitution."
In a statement on behalf of the Supreme Court and retired Justices, Chief Justice John Roberts called Scalia, "an extraordinary individual and jurist, admired and treasured by his colleagues."
"His passing is a great loss to the Court and the country he so loyally served. We extend our deepest condolences to his wife Maureen and his family," he added.

Scalia's replacement to the court would be President Obama's third nomination. He previously nominated Justices Sonia Sotomayor and Elena Kagan. But CBS News Chief Legal Correspondent Jan Crawford said it is unclear whether the Republican-held Senate will entertain a nomination from Mr. Obama or wait for a new president to be elected this November.
"It could be very unlikely that President Obama that will get that nomination," Crawford said. "This court could remain with eight justices until the next president takes office. I think that's very unclear what will happen."
"This vote will change the balance of the Supreme Court if a liberal is nominated," she added.
Sen. Ted Cruz, R-Texas, one of the 2016 presidential candidates, said the responsibility should fall to the next president.
