WASHINGTON (AP) — The Supreme Court is hearing arguments this week with profound legal and political consequences: whether former President Donald Trump is immune from prosecution in a federal case charging him with plotting to overturn the results of the 2020 election.

In addition to establishing a potentially historic ruling about the scope of presidential power, the court’s decision — whenever it comes — will undoubtedly go a long way in determining a trial date for Trump in one of the four criminal prosecutions that the presumptive Republican presidential nominee faces.

A quick decision in the Justice Department’s favor could conceivably put the case on track for trial this fall. But if the court takes until late June to resolve the question, then the likelihood rises substantially that the November presidential election will happen without a jury ever being asked to decide whether Trump is criminally responsible for efforts to undo an election he lost in the weeks leading up to the violent Jan. 6, 2021, riot at the U.S. Capitol.
