Answer 1

The supremacy clause of the U.S. Constitution allows federal law to override state law.

Article 6, Paragraph 2 of the US Constitution reads: "This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby, any Thing in the Constitution or Laws of any State to the Contrary notwithstanding."
