Does Judge Cannon Have Jurisdiction?

Normally a search warrant is issued by a judge who has jurisdiction over the matter. And so here the Trump folks file a civil action before the district court. Judge Cannon just kind of takes over the case and that strikes me as odd, although less odd than a lot of the other things going on here at least less far reachingLess problematic than some of the other thing. So she says that she does have jurisdiction and she kind of invokes this equitable remedy, which is supposed to be pretty extraordinary.
