Supreme Court Justice Ketanji Brown Jackson told a group of lawyers and judges on Thursday that "the state of our democracy" is what keeps her up at night.

Jackson did not say what, specifically, concerned her about the state of democracy, though she has recently written a series of scathing dissents.

The justice has emerged as one of the court’s sharpest critics, issuing more dissents than any colleague during the Supreme Court term that ended last month.
