President Trump said in a tweet late Monday that starting next week, US Immigration and Customs Enforcement will remove “millions” of immigrants who have entered the United States illegally.


The tweet was in apparent reference to an administration plan for ICE to round up large groups of migrants in a widespread move across major US cities.





An ICE immigration sweep in December resulted in 58 arrests across New England.

Trump also praised Mexico in the Monday tweet and suggested that Guatemala was close to signing a “safe-third agreement,” which could legally prevent migrants who pass through that country from eventually applying for asylum in the United States. Mexico has refused to sign such a deal with the United States, which has only one active safe-third agreement, with Canada.

The president had previously threatened tariffs on Mexico over the movement of Central and South American migrants through the country on their way to the United States.
