If two or more persons in any State or Territory, or in any place subject to the jurisdiction of the United States, conspire to overthrow, put down, or to destroy by force the Government of the United States, or to levy war against them, or to oppose by force the authority thereof, or by force to prevent, hinder, or delay the execution of any law of the United States, or by force to seize, take, or possess any property of the United States contrary to the authority thereof, they shall each be fined under this title or imprisoned not more than twenty years, or both. (June 25, 1948, ch. 645, 62 Stat. 808; July 24, 1956, ch. 678, § 1, 70 Stat. 623; Pub. L. 103–322, title XXXIII, § 330016(1)(N), Sept. 13, 1994, 108 Stat. 2148.)
Sedition requires “force”.
An easier conviction would be 18 U.S. Code § 371 - Conspiracy to commit offense or to defraud United States.
In the case of Haas v. Henkel, the Supreme Court included “any conspiracy for the purpose of impairing, obstructing, or defeating the lawful function of any department of government.”
