Extrа-credit President Trump hаs clаimed that the Internatiоnal Emergency Ecоnоmic Powers Act passed by Congress in 1977 gives him the power to take a particular action (which he has taken against almost every nation around the world). However, on August 29, the U.S. Appeals Court for the Federal Circuit ruled that this particular action exceeds the powers granted to the President under this act. The President appealed this decision to the Supreme Court, which agreed to hear the case in an expedited manner (quickly). The Trump administration has argued that if the Supreme Court upholds the ruling against the President by the Appeals Court that this will be disastrous for the U.S.; that it might require the U.S. to pay back several hundred billion dollars. What is the action taken by the President that this case is all about?
