The Pres. can "Federalize" the National Guard even during a "State" emergency.
"Posse Comitatus", as modified in 1981, refers to the Armed Forces of the United States. It does not apply to the National Guard under state authority from acting in a law enforcement capacity within its home state or in an adjacent state if invited by that state's governor. The United States Coast Guard, which operates under the Department of Homeland Security, is also not covered by the Posse Comitatus Act, primarily because the Coast Guard has both a maritime law enforcement mission and a federal regulatory agency mission.[/quote]
