WASHINGTON (AP) — The search for Supreme Court Justice Anthony Kennedy's replacement has begun. President Donald Trump said Wednesday he'll choose a replacement from "an excellent list" of 25 candidates.

Kennedy on Wednesday announced his retirement after three decades on the court, giving Trump a chance to solidify a conservative majority on the high court. Doing so was one of his campaign promises in 2016. His confirmation of Justice Neil Gorsuch last year was considered a key victory by anti-abortion groups and other conservatives.

A look at a few judges who are considered to be top candidates to replace the 81-year-old Kennedy. All appear on Trump's list.

THOMAS HARDIMAN
Hardiman went to the University of Notre Dame as the first person in his family to go to college. He financed his law degree at the Georgetown University Law Center by driving a taxi. He became a federal district judge at 37 and was appointed to the 3rd Circuit in 2007. He turns 53 on July 8. Hardiman has sided with jails seeking to strip-search inmates arrested for even minor offenses and has supported gun rights. He dissented in a 2013 case that upheld a New Jersey law to strengthen requirements for carrying a handgun in public. A Massachusetts native, Hardiman settled in Pittsburgh, where his wife comes from a family of prominent Democrats.

BRETT KAVANAUGH
The Yale-educated appellate court judge for the District of Columbia recently wrote a dissent when his colleagues allowed an immigrant teen in U.S. custody to have an abortion. Kavanaugh also clerked for Justice Kennedy. He served as an associate independent counsel during the Whitewater investigation into the Clintons' land deal, as well as in the White House under President George W. Bush. He's 53.

WILLIAM PRYOR JR.
The federal appeals court judge from Mobile, Alabama, is also a former attorney general of the state and an alumnus of Northeast Louisiana University and Tulane University law school. In 2003, he called for the removal of Alabama Chief Justice Roy Moore, who had refused a federal court order to remove the Ten Commandments from a judicial building. Trump backed Moore in a Senate race last year despite charges of sexual misconduct with young women. Moore lost the race.

President George W. Bush nominated Pryor to the federal appellate court in 2004. President Barack Obama named him to the U.S. Sentencing Commission in 2013. Pryor is 56.
