President Donald Trump is expected to put forth a nominee to fill Ruth Bader Ginsburg’s seat on the Supreme Court in the coming days, multiple sources close to the president and with direct knowledge of the situation told ABC News.

The sources describe the list of potential nominees as very short and including at least one woman. U.S. Circuit Judge Amy Coney Barrett is seen as a leading contender, two sources tell ABC News.

Trump was asked about Ginsburg’s death after leaving his Friday night campaign rally in Minnesota and said he was not aware of her passing. The 87-year-old justice died Friday after a battle with pancreatic cancer, the court announced.
