The death of Justice Ruth Bader Ginsburg leaves vacant a crucial seat on the U.S. Supreme Court. Based on reporting prior to her sudden death, here are some of the top contenders to fill that seat, should President Trump choose to nominate someone.

Each of these names is on Trump's list of possible nominees, a list he has said he would rely on when making any selection.

Judge Amy Coney Barrett, 7th Circuit U.S. Court of Appeals

Born in 1972, Coney Barrett is a former Notre Dame Law School professor. Her 2017 confirmation to the federal bench was contentious, with several Democratic senators questioning whether her faith -- expressed in prior speeches -- would influence her jurisprudence. "The dogma lives loudly within you, and that's a concern," said Sen. Dianne Feinstein, D-Calif. Barrett responded, "It's never appropriate for a judge to impose that judge's personal convictions, whether they arise from faith or anywhere else, on the law." Barrett was a former law clerk for the late Justice Antonin Scalia.

Born in 1963, Gruender is a conservative colleague of Colloton and a former U.S. Attorney. He authored a 2008 opinion upholding South Dakota's "informed consent" for those seeking an abortion to be told about the consequences of the procedure.

Judge Thomas Hardiman, 3rd Circuit U.S. Court of Appeals, chambers in Pittsburgh

Born in 1966, Kethledge clerked for Justice Anthony Kennedy and was in private practice before joining the appeals court in 2008. But it took more than two years to get the nomination confirmed, after Michigan's two Democratic U.S. senators raised objections in a larger fight over Bush's judicial nominees.

TRIBUTES TO GINSBURG POUR IN FROM ACROSS POLITICAL SPECTRUM

Judge Joan Larsen, 6th Circuit U.S. Court of Appeals

Born in 1968, Larsen was a former law clerk to Scalia, who delivered one of the tributes to the late justice at his memorial service in March. She served in the Justice Department office that produced the legal justifications for the enhanced interrogation techniques, including waterboarding, that critics have called torture. She was on the Michigan Supreme Court only since 2015, winning a state election a year later, when she was tapped for the federal bench in 2017.

Judge Barbara Lagoa, 11th Circuit U.S. Court of Appeals

Born in 1967, Lagoa is a former Florida Supreme Court justice, appointed in 2019 by Gov. Ron DeSantis, the first Cuban American woman to serve on that court. She was nominated to the 11th Circuit by Trump in October 2019.

Justice Thomas Lee, Utah Supreme Court

Born in 1964 to a prominent political and legal family, Lee is the son of Rex Lee, a former solicitor general in the Reagan Justice Department, and the brother of Mike Lee, a U.S. senator, who is also on Trump's list. Lee clerked for Justice Thomas and teaches part-time at Brigham Young's law school.

MCCONNELL SAYS TRUMP NOMINEE WILL GET VOTE ON SENATE FLOOR

Judge David Stras, 8th Circuit U.S. Court of Appeals, chambers in Minneapolis

Born in 1974, Stras served on the Minnesota Supreme Court and is believed to be the first Jewish member of the state's high court. He, too, clerked for Justice Thomas and once headed the Institute for Law and Justice, a well-respected academic think tank on public policy and judicial politics. Stras was nominated in 2017 to sit on the appeals court.

Judge Allison Jones Rushing, 4th Circuit U.S. Court of Appeals

Born in 1982, Rushing clerked for Thomas and then-Judge Gorsuch before being appointed in 2019 by Trump.

Judge Don Willett, 5th Circuit U.S. Court of Appeals, chambers in Austin

Born in 1966, Willett worked in the George W. Bush presidential campaign and administration in various roles, before joining the Texas Supreme Court. One of seven finalists to fill the Scalia vacancy, Willett was nominated to the federal bench by Trump. He is perhaps best known for his heavy use of social media and his Twitter handle, @justicewillett, which has more than 98,000 followers. But speaking in that capacity, Willett has repeatedly tweaked Trump on Twitter, such as this mock quote from the GOP nominee: "'We'll rebuild the Death Star. It'll be amazing, believe me. And the rebels will pay for it.'   --Darth Trump"
