President Donald Trump will select his next Supreme Court nominee from the same list of 21 candidates his campaign produced during the 2016 general election, should another vacancy arise on the high court.

The president told The Washington Times that the list of prospective nominees has been integral to his political success, and vowed to name his next nominee from the same roster.

“Yes,” Trump said when asked if he would stick to the list for future Supreme Court nominations. “That list was a big thing.”

He also raised the prospect of Justice Anthony Kennedy’s imminent retirement. Though Kennedy — who will turn 81 in July — has not suggested he is mulling retirement in public remarks, rumors have circulated among court-watchers for nearly a year that he will soon leave the bench.
