The 11th Circuit is allotted five judges from Florida, four from Georgia and three from Alabama.

Trump previously filled two Georgia seats with former Georgia Supreme Court Justice Britt Grant and former Georgia Court of Appeals Judge Elizabeth Branch. Trump filled an Alabama seat with former state Solicitor General Kevin Newsom.

Last month, Judge Gerald Tjoflat told Trump that he, too, will take senior status. Trump has yet to nominate Tjoflat's successor.

Trump’s nominees to succeed Marcus and Tjoflat must be from Florida, because Marcus’ chambers are in Miami and Tjoflat’s are in Jacksonville.

The 11th Circuit court often hears appeals of great importance, such as cases involving the death penalty, voting rights, immigration, discrimination in the workplace and convictions obtained by federal prosecutors.

Marcus said he will continue to stay busy as a senior judge.

“I am deeply grateful for the opportunity I’ve had to serve on two extraordinary courts,” Marcus said in a statement released Thursday.

His judicial colleagues over the past 34 years, he said, “are a superb group of legal scholars and jurists of the highest caliber and it is a great honor to have served with them.”
