U.S. Marshals are being sent in to guard the Hawaii judge that blocked the Trump administration's second travel ban.
U.S. District Judge Derrick Watson reportedly received death threats after issuing a nationwide halt on the ban in mid-March.
Watson blocked the ban hours before it was set to take effect. Lawyers for the state of Hawaii argued the revised order violated the First Amendment's establishment clause.
If that sounds familiar, it's because it is.
The second ban looks similar to the first — it's aimed at keeping people from six Muslim-majority countries from entering the U.S. for 90 days. The revision nixed Iraq from the ban.
Both bans suspended the U.S. refugee program for 120 days.
Authorities haven't said how the threats against Watson were made. The FBI says its also prepared to offer protection.
