Here is the text of the bill. It seems to exclude US citizens in the section below

(b) Applicability to United States Citizens and Lawful Resident Aliens-
(1) UNITED STATES CITIZENS- The requirement to detain a person in military custody under this section does not extend to citizens of the United States.
(2) LAWFUL RESIDENT ALIENS- The requirement to detain a person in military custody under this section does not extend to a lawful resident alien of the United States on the basis of conduct taking place within the United States, except to the extent permitted by the Constitution of the United States.

Below is everything in context. It appears to me that the ACLU article is inaccurate but I could be wrong.
