I’m guessing the charge will be along the lines of “terroristic threatening” or something like that for the news people who received a fake bomb. For the members of Congress, it’s more serious under 18 U.S.C. § 115 – U.S. Code.
Whoever assaults, kidnaps, or murders, or attempts or conspires to kidnap or murder, or threatens to assault, kidnap, or murder, any person who formerly served as a person designated in paragraph (1), or a member of the immediate family of any person who formerly served as a person designated in paragraph (1), with intent to retaliate against such person on account of the performance of official duties during the term of service of such person, shall be punished as provided in subsection (b).
