What to listen for during Supreme Court arguments on Donald Trump and presidential immunity

The Supreme Court will hear arguments over whether Donald Trump is immune from prosecution in a case charging him with plotting to overturn the results of the 2020 presidential election. Thursday's hearing is a historic day for the court, with the justices having an opportunity to decide once and for all whether former presidents can be prosecuted for official acts they take while in the White House. But between a decades-old case about Richard Nixon, and an obscure constitutional provision about presidential impeachments, there are likely to be some unfamiliar concepts and terms thrown about.
