President Donald Trump has asked advisers their opinions about nominating Utah Senator Mike Lee to replace Justice Anthony Kennedy on the Supreme Court, according to three people familiar with the matter.

It remains early in the selection process for a nomination that will be a crucial part of Trump's legacy, choosing a justice who is likely to serve on the court for decades and cement its ideological balance to the most conservative in generations.

Trump hasn't settled on a favorite yet for the nomination, two of the people said. And even as the president mulls the 47-year-old Lee as a potential choice, the search for Kennedy's successor remains wide open.
