The Trump administration said it accidentally told some Ukrainian refugees they needed to leave the US immediately because their legal status was being revoked, telling CBS News the following message was sent by mistake: "DHS is now exercising its discretion to terminate your parole," the 3 April notice said, referring to the temporary legal status that the Biden administration granted to hundreds of thousands of Ukrainians. "Unless it expires sooner, your parole will terminate 7 days from the date of this notice. Again, DHS is terminating your parole. Do not attempt to remain in the United States " the federal government will find you," the notice warned. "Please depart the United States immediately." Roughly 240,000 Ukrainians are safe in the US under a policy known as Uniting for Ukraine (U4U). DHS retracted the email without apology or explanation.
