Samuel Anthony Alito Jr. (/əˈliːtoʊ/ ə-LEE-toh; born April 1, 1950) is an American lawyer and jurist who serves as an associate justice of the Supreme Court of the United States. 

He was nominated by President George W. Bush on October 31, 2005, and has served since January 31, 2006.[2] He is the second Italian-American justice to serve on the U.S. Supreme Court, after Antonin Scalia, and the eleventh Roman Catholic.

Raised in Hamilton Township, New Jersey, and educated at Princeton University and Yale Law School, Alito served as the U.S. Attorney for the District of New Jersey and a judge on the U.S. Court of Appeals for the Third Circuit before joining the Supreme Court. He is the 110th justice.

In 2013 Alito was considered "one of the most conservative justices on the Court".[3] He has described himself as a "practical originalist".[4] Alito's majority opinions in landmark cases include McDonald v. Chicago, Burwell v. Hobby Lobby, Murphy v. NCAA, and Janus v. AFSCME.

While Justice Clarence Thomas spent 63 pages in a 6-3 majority opinion Thursday painstakingly explaining the court's reasons for striking down a New York conceal carry gun law and changing the way judges will analyze a host of other gun regulations going forward, his colleague Samuel Alito took a different tack.

In a sparse but relentlessly caustic concurring opinion, the conservative Alito criticized his liberal colleagues for their dissent, blasting them for attempting to "obscure" the specific question the court had decided, and for referencing the recent mass shootings that have shocked the nation.

The fact that Alito, who joined Thomas' opinion in full, chose to also strike out alone against the dissenters highlights the current tension on the court triggered by a blockbuster docket and the unprecedented leak of a draft majority opinion in May overturning Roe v. Wade.

Alito authored that draft opinion, which if it stands, will likely trigger an angry dissent from the liberal justices. The abortion opinion could come as early as Friday.

Already, the liberals and conservatives have openly sparred in opinions. On Tuesday, for instance, Justice Sonia Sotomayor ended one dissent in a religious liberty case that broke down along ideological lines with this warning: "With growing concern for where this Court will lead us next, I respectfully dissent.

In his concurrence in the gun case he took on the liberal dissent penned by Justice Stephen Breyer and joined by Sotomayor and Justice Elena Kagan.
