To me it looks as though these sections are exclusive (right word?) - meaning separate usages of the act. IOW, the first one requires the requset of legislature or governor if legislature can’t, of disturbances in that state. But the other usages seem to be indepdenent of the state’s request. Informed legal knowledge welcome.

Weaponized COVID, assassination attempt?
Two White House reporters caught nearly identical ‘rare’ strains of coronavirus, gene sequencing study finds
Fred Hutchinson Cancer Research Center scientists sequenced the genomes of coronavirus samples taken from two people linked to the White House Outbreak
The New York Times says that those two people were journalists Michael Shear and Al Drago
Drago covered the Judge Amy Coney Barrett
‘superspreader’ event and Shear was on Air Force One with President Trump
Each person had a similar but ‘rare’ strain of coronavirus for the US, the researchers say in a study that has not yet been peer-reviewed
They say this finding makes it likely the two journalists - who say they had no prior contact - got coronavirus in the same outbreak
Testing others in the White House might help locate the source of infection, but the White House turned down CDC’s offer for contact tracing help
Yes the forces can be invited or imposed. Real governors would handle it, as we have seen some don’t. During Rodney King riots, the governor requested the assistance.
