The Trump administration has transferred hundreds of immigrants to El Salvador even as a federal judge issued an order temporarily barring the deportations under an 18th century wartime declaration targeting Venezuelan gang members,

The immigrants were deported after Trump’s declaration of the Alien Enemies Act of 1798, which has been used only three times in U.S. history.

The Trump administration said Sunday that hundreds of individuals were deported from the country after President Donald Trump invoked a sweeping wartime authority to speed up the deportations of migrants affiliated with the Venezuelan gang Tren de Aragua.
