There is nothing like making a broad, sweeping assertion that is wrong. By statute, jurisdiction for a writ of quo warranto is with the U.S. District Court for the District of Columbia. (See below.) However, if a state is a party, the U.S. Constitution (Article III, Sec. 2), grants that state the right to file for that writ in the U.S. Supreme Court.

Code of the District of Columbia
Actions Against Officers of the United States.
§ 16–3501. Persons against whom issued; civil action.
A quo warranto may be issued from the United States District Court for the District of Columbia in the name of the United States against a person who within the District of Columbia usurps, intrudes into, or unlawfully holds or exercises, a franchise conferred by the United States or a public office of the United States, civil or military. The proceedings shall be deemed a civil action.
