Although we haven’t seen that DHS Office of the General Counsel determination, DHS’s acting general counsel at the time was Joseph Mazzara.

Mazzara was most recently in the news for acknowledging that he was the person who gave DHS Secretary Kristi Noem legal advice about whether or not to turn around the Alien Enemies Act flights the night of March 15 after Chief Judge James Boasberg ordered the administration to do so. (They did not turn the flights around.)

Sometime less than two months later, per Lyons, Mazzara’s office took on the Fourth Amendment as well.
