Where it stands: Atlanta; Detroit; Indianapolis; D.C.; Los Angeles; Myrtle Beach, South Carolina; Denver; Santa Monica, California; Chicago; Dallas; Philadelphia; San Jose; Salt Lake City; and Cleveland have imposed curfews for Sunday night.

Rochester Mayor Lovely Warren said Monday she's fired Police Chief La'Ron Singletary and suspended two others following protests over the police killing of Daniel Prude, a Black man says after being hooded and held down by local police.

Why it matters: The firing of Singletary comes almost a week after he announced his retirement. Activists have called for Singletary's resignation after details of Prude's March death surfaced recently, the Democrat and Chronicle notes. Warren accused Singletary of failing to properly brief her on the killing.

President Trump said Judge Amy Coney Barrett's Senate confirmation to the Supreme Court and her subsequent taking of the constitutional oath Monday was a "momentous day," as she she vowed to serve "without any fear or favour."

Of note: As Republicans applauded the action, Democratic leaders warned of consequences to the rush to replace the late liberal Justice Ruth Bader Ginsburg with a conservative so close to the election, as progressives led calls to expand the court.
