A monumental Supreme Court term is set to begin with major tests of presidential power on the agenda. There also are important cases on voting and the rights of LGBTQ people. The court’s conservative majority has far been receptive, at least in preliminary rulings, to many of President Donald Trump’s aggressive assertions of authority. They could be more skeptical when they conduct an in-depth examination of some Trump policies, including the Republican president’s imposition of tariffs and his desired restrictions on birthright citizenship. The new term gets underway Monday.
