Sen. Kamala Harris (D–Calif.), who is seeking the 2020 Democratic presidential nomination, says that if elected she will push legislation that would authorize federal courts to issue gun confiscation orders against people who express opinions that may indicate an intent to commit a hate crime. These “domestic terrorism prevention orders” would “temporarily restrict a person’s access to guns if they exhibit clear evidence of dangerousness,” including “violent racist threats or anti-immigrant manifestos.”
