President Donald Trump is planning to invoke wartime authority in the coming days to rapidly accelerate the deportation of immigrants, according to people familiar with the matter.

In the lead-up to the presidential election, Trump said he would carry out the “largest deportation program” in U.S. history—though efforts appear to have slowed down.

Experts predict a swift legal challenge to Trump's 'novel' approach of invoking wartime powers to target immigration.

Legal contributor Kim Wehle explains the wartime law, as well as the Trump administration asking the Supreme Court to narrow nationwide injunctions blocking an order redefining birthright citizenship.

The act is a wartime authority that allows the president to detain and deport non-U.S. citizens from enemy countries.

Authorities plan to mainly target members of Tren de Aragua, a violent Venezuelan gang.
