Veto was considered unconstitutional and the Supreme court actually ruled 6-3 declaring that this law was Unconstitutional. Many presidents argued that the law was unconstitutional which then resulted in the Supreme court declaring that it was in fact unconstitutional.
Other reasons would be the information provided in the question.
