I don't believe there is any connection to the US v. Robinson case...but I may be wrong. If this has already been covered in another thread, I will edit this OP.

We recently scored a major victory in the federal civil rights lawsuit Robinson vs. Sessions, now on appeal to the Second Circuit Court of Appeals. The US DOJ Attorneys admitted in their Answering Brief that the FBI screens “all” Americans seeking to lawfully purchase a firearm against the Terrorist Screening Database (“TSDB”) upon submission of the ATF Form 4473. Since 2004, as part of its background checks for all potential firearms purchasers, the NICS has searched a file containing a list of known or suspected terrorists that is exported by the Terrorist Screening Center from the TSDB into the FBI’s National Crime Information Center database.
