Story highlights Diane Sykes and William Pryor are among the top contenders

Trump is considering a long list looking to replace the late Antonin Scalia

Washington (CNN) It will be some time before Donald Trump announces a nominee to fill the vacancy left by Antonin Scalia, according to transition insiders.

But two names continue to emerge to the top of the president elect's list of potential Supreme Court justices. Judges Diane Sykes and William Pryor are among the top contenders, according to multiple sources familiar with the process.

The Supreme Court vacancy is "actively being discussed," but there is no timetable at the moment, Trump transition aide Jason Miller told reporters Thursday.

"The President-elect, he had previously put out a list of 20 very qualified individuals from which he would select. I know that they have continued to narrow that list down," Miller said. "He himself has said that's probably a shorter list of 5 or 6 folks that are near the top of that, that's being narrowed down to. And again, but this is another one where it's an absolute utmost priority, so we need to make sure we get this one right."
