Judicial halt of deportation flights puts US foreign policy at risk, career State Dept official claims

The flights also included alleged members of the violent gang Tren de Aragua (TdA). 

Kozak noted the possibility "that foreign interlocutors might change their minds" over accepting certain individuals associated with TdA "or might otherwise seek to leverage this as an ongoing issue."

"These harms could arise even in the short term, as future conversations with foreign interlocutors seeking to resolve foreign policy matters would need to take this issue into account along with other issues, instead of allowing the discussions to fully move on to the other issues," Kozak wrote. 

Kozak did not further expand upon the "harms" that could arise as a result of Boasberg's order in his declaration. The State Department declined to comment on pending litigation. 

"TDA is one of the most violent and ruthless terrorist gangs on planet earth," White House Press Secretary Karoline Leavitt told Fox News Digital in a statement. "They rape, maim and murder for sport. TDA is responsible for some of the most heinous crimes that have occurred on US soil in recent years, including the murders of Laken Riley and Jocelyn Nungaray. TDA is a direct threat to the national security of the United States."

Boasberg sided with the plaintiffs, Democracy Forward and the ACLU in granting the emergency order and ruling that the deportations would likely pose imminent and "irreparable" harm. 

"Given the exigent circumstances that [the court] has been made aware of this morning, it has determined that an immediate Order is warranted to maintain the status quo until a hearing can be set," Boasberg wrote. 

In a Monday-evening hearing, Boasberg proceeded to ask the Trump administration to submit more information regarding the flights.

Both parties are ordered to appear back in court on Friday.

The motion also argued that the administration's "Proclamation" and its implementation "are perfectly lawful."

"Under his authority to protect the nation, the President determined that TdA represents a significant risk to the United States, that it is intertwined and advancing the interests of a foreign government in a manner antithetical to the interests of the United States, and that its members should be summarily removed from this country as part of that threat," the motion continued.
