Running out of federal court vacancies to fill, Senate Republicans have been quietly making overtures to sitting Republican-nominated judges who are eligible to retire to urge them to step aside so they can be replaced while the party still holds the Senate and the White House.

Senator Mitch McConnell, Republican of Kentucky, who has used his position as majority leader to build a judicial confirmation juggernaut for President Trump over the past three years, has been personally reaching out to judges to sound them out on their plans and assure them that they would have a worthy successor if they gave up their seats soon, according to multiple people with knowledge of his actions.
