The US Coast Guard is taking President Donald Trump’s anti-immigrant mandate seriously, announcing this week it will step up patrols in migrant-prone crossings.

More than a million migrants who were allowed to enter the United States during the Biden administration may have their temporary stays revoked and be rapidly deported, according to an Immigration and Customs Enforcement document that became public Friday.
