When the justices take the bench for oral arguments on Wednesday, one seat will be empty: Justice Amy Coney Barrett, the junior member of the court’s conservative supermajority, has recused herself from the case, which means she will not take part in the oral arguments, deliberations or vote.

The Supreme Court will hear arguments Wednesday in a case that could have “profound consequences” for schools across the country, according to a warning from Oklahoma’s Republican attorney general. He’s sounding the alarm on what would happen if the justices approve the nation’s first public religious charter school.
