Donald Trump suggested in an interview Wednesday evening that a list he had released hours earlier, revealing 11 individuals he would consider nominating for the Supreme Court, might not actually include his top pick.

"I thought what I would do is put this forward and this would be the list that I would either choose from or pick people very close in terms of the spirit and the meaning of what they represent," the presumptive Republican presidential nominee said in an hour-long interview with Fox News' Sean Hannity.

"We're either going to choose from this list or people very close to it," he said. "At a minimum, we will keep people from this general realm."

Trump claimed that "outside of the defense of our country," filling vacancies on the high court will likely be the "single most important thing" the next U.S. president must do while in office.

"I want high-intellect. I want great intellect," the billionaire said, adding that the potential nominees included on his list "are all high-intellect."

"They're pro-life," Trump said.

Trump's list included a handful of judges on the U.S. Court of Appeals for the Eighth Circuit as well as several justices on state supreme courts.

Among those on the list were Thomas Lee, the brother of Sen. Mike Lee (R-Utah), and Diane Sykes, the ex-wife of conservative radio host Charlie Sykes, who blasted Trump repeatedly on his program ahead of the Wisconsin primary in April.

Trump promised to release a list of potential nominees nearly two months ago, after being pressured to prove his conservative credentials.
