Supreme Court Justice Antonin Scalia, the longest-serving Supreme Court Justice, reportedly died today at age 79 of natural causes.

From Texas Gov. Greg Abbott:

Justice Antonin Scalia was a man of God, a patriot, and an unwavering defender of the written Constitution and the Rule of Law. He was the solid rock who turned away so many attempts to depart from and distort the Constitution. His fierce loyalty to the Constitution set an unmatched example, not just for judges and lawyers, but for all Americans. We mourn his passing, and we pray that his successor on the Supreme Court will take his place as a champion for the written Constitution and the Rule of Law. Cecilia and I extend our deepest condolences to his family, and we will keep them in our thoughts and prayers.
