The number of people at Donald Trump's controversial immigrant detention centre "Alligator Alcatraz" has dropped by half following a judge's order to close much of the facility, according to border tsar Tom Homan.
US media, citing internal emails between Florida officials, report the centre could be empty within "days".
The facility - located deep in the swampy Florida Everglades - opened in July to support the Trump administration's mass deportation drive.
It quickly drew multiple legal challenges over alleged poor conditions and environmental damage to the delicate ecosystem of the Everglades, a Unesco world heritage site.
Last week, a federal judge issued a preliminary injunction halting expansion of the facility, and ordering its operations wound down, with all detainees to be relocated within 60 days.
