Recently, Trump placed a travel ‘ban’ on non-citizens of the US and people from some other countries without direct relations with citizens of the US from travelling to the US during the pandemic.
All executive powers are explicitly stated in Article II of the United States Constitution no? If so, what part of Article II gives the president the ability to ban travel in any way, as no part of the Constitution even states the word “travel”. What executive powers for the president of the United States are implied? The president has the ability to make executive orders without congressional approval, and they take the same affect as a law. Where in Article II is there anything about executive orders?
What implied powers are not stated in Article II of the US Constituion, but are also non-disputed over and why is this?
