His speech to the conservative legal organization symbolized how much had changed since President Barack Obama's unsuccessful nomination of Judge Merrick Garland to the high court and President Donald Trump's election last November.
Trump's original list was released in September 2016 before he was elected president, and included then-Colorado federal appeals court Judge Neil Gorsuch, who now sits on the Supreme Court in the seat left vacant by the late Justice Antonin Scalia.
Gorsuch is the first Coloradan to serve on the Supreme Court since Byron White retired in 1993.
"The President remains deeply committed to identifying and selecting outstanding jurists in the mold of Justice Gorsuch", the White House said in a statement. "I've been a member of the Federalist Society since law school, still am".
Catherine Glenn Foster, president of the anti-abortion advocacy group Americans United for Life, said she was pleased with the new selections. "You never know when there will be a vacancy".
One possibility is its use as a subtle political signal.
The additional names come even as Trump adviser Leonard Leo, executive vice president of the Federalist Society, said there is no indication the 81-year-old Kennedy or any other justice is planning to leave the court. Republicans now have 52 votes in the Senate and would need at least 50 to confirm a new justice, with the tie-breaking vote of Vice President Pence.
Other additions to the list include U.S. appeals court Judges Amy Barrett and Kevin Newsom, and state supreme court Judges Britt Grant of Georgia and Patrick Wyrick of Oklahoma.
Two of them are appellate judges who were nominated by Trump earlier this year and confirmed by the Senate: Amy Coney Barrett and Kevin Newsom. She drew sharp questions about her Catholic faith from Democrats during her confirmation hearings, prompting Republicans to complain about "Catholic bigotry". Allow beforehand clerked for Kavanaugh at the D.C. Bids Court.
The White House on Friday released an updated list of 25 potential Supreme Court nominees.
Judicial Crisis Network chief counsel and policy director Carrie Severino called the new candidates "some of the best and brightest judges in the nation". "They represent a diverse range of backgrounds, including both state and federal judges, three who were former state solicitors general with firsthand experience protecting our constitutional balance of powers".
