Welcome to Supreme Court Brief and the final day of the January argument session. The justices return to campaign finance law in a challenge originally brought by the campaign of Sen. Ted Cruz. We take a look at competing amicus briefs, one of which was written by former Trump White House counsel Donald McGahn. And we briefly examine the court’s “mask mystery,” which has occupied court watchers during this month’s arguments. Scroll down to read about another possible Covid legal dispute on the justices’ radar.
