After an Afghan national was arrested in the shooting of two National Guard members in the nation's capital, Trump called for reverse migration.

The State Department and the Department of Homeland Security have also used the term remigration in social media and planning documents.

Heidi Beirich of the Global Project Against Hate and Extremism says European white nationalists use remigration to refer to the ethnic cleansing of non-white people.

The White House, State Department, and DHS rejected or did not acknowledge questions about the term's link to an extremist movement.
