The Department of Justice has issued a federal warrant for the arrest of an illegal immigrant who on Thursday was acquitted of murder charges in the 2015 killing of Kate Steinle in San Francisco.

A jury found Jose Ines Garcia Zarate, a Mexican immigrant who has been deported multiple times only to return to the U.S., not guilty of murder and charges of involuntary manslaughter and assault with a deadly weapon. He was convicted of being a felon in possession of a firearm.

The Department of Justice on Friday unsealed the arrest warrant, which accuses Zarate of violating his supervised release, in the Western District of Texas, the Hill reported.

In 2015, Zarate was released from jail, despite the federal government having a detainer request for him. The Department of Justice may be considering federal charges in connection to Steinle's death.

Sanctuary cities, jurisdictions that do not fully cooperate with federal immigration authorities, became a major issue after Steinle's death. San Francisco, where she was killed, is a sanctuary city.

President Donald Trump castigated the verdict in the Steinle case on Twitter, calling it "disgraceful."
