Deploying unidentifiable federal agents — without the consent or request of the Governor, County Executive, or Mayor — to the city about to host the opposing party’s convention to nominate his challenger in the November election is not merely provocative, it is terrorism:

[T]he term “terrorism” means premeditated, politically motivated violence perpetrated against noncombatant targets by subnational groups or clandestine agents.

— 22 U.S. Code § 2656f(d)(2)

[T]he term “domestic terrorism” means activities that (A) involve acts dangerous to human life that are a violation of the criminal laws of the United States or of any State; (B) appear to be intended (i) to intimidate or coerce a civilian population; (ii) to influence the policy of a government by intimidation or coercion; or (iii) to affect the conduct of a government by mass destruction, assassination, or kidnapping; and (C) occur primarily within the territorial jurisdiction of the United States.

— 18 U.S. Code § 2331.5, as modified by the USA PATRIOT Act

The resident of the White House is literally using violent, masked federal agents in a terrorism campaign against residents of the city, county, and state hosting the nominating convention for his challenger in an election just over 100 days from now, a state he won four years ago, but where where the latest polling has him trailing 49% to 41%.
