Supreme Court Justice Samuel Alito rejects calls to quit Supreme Court cases on Trump and Jan. 6

Supreme Court Justice Samuel Alito has decided not to recuse himself from cases related to the January 6th Capitol assault, despite calls from House Democrats. The calls for recusal were based on reports of an upside-down American flag, a symbol of the Stop the Steal movement, being displayed outside his home. Alito attributed this to his wife and rejected the recusal requests.
