Answer:
Hello!!! erz here ^^
Explanation:
The majority of Congress must vote no to the bill. If a bill is passed, the Pres. can veto the bill; however, the bill can still be passed if 2/3s of both the Senate and House of Representatives passed the bill. Lastly, the bill could come under a constitutional challenge and the Supreme Court of the US will determine whether the bill is constitutional... if yes.. the law stays... if no... well you get the idea
